Automated and Electric Vehicles Bill (Second sitting)

(Limited Text - Ministerial Extracts only)

Committee Debate: 2nd sitting: House of Commons
Tuesday 31st October 2017 Public Bill Committees

[The Chair]

It is not necessary for all the witnesses to answer all the questions. I am anxious as many colleagues as possible get in. I know the Minister is anxious for his voice to be heard, which we await with alacrity.

[The Minister for Transport Legislation and Maritime (Mr John Hayes)]

Q Thank you, Sir Edward. Steve, you were previously very supportive of the Vehicle Technology and Aviation Bill, the forerunner of this Bill, particularly of the measures on AVs. Can you tell me why and why you think it is right that the Government bring this kind of legislation forward now? How important is it that in order to encourage further development we establish a legislative framework?

Steve Nash: We are going through what is the biggest change in the industry—

[Mr Hayes]

Sorry, I directed the question to Mr Gooding

Steve Nash: Sorry, I beg your pardon.

Steve Gooding: There are two Steves.

[Mr Hayes]

That is the trouble with two Steves. I do apologise.

Steve Gooding: I am sure Steve will come in in a second. Yes, the foundation has been very supportive of both aspects of the Bill before you today. Specifically on the electric vehicle side, we think that while there have been significant percentage increases in the take up of ultra-low emission vehicles, they are still a tiny fraction of the overall vehicle park. There are many reasons why the ordinary consumer could get confused by what is on offer to them with various different charging packages for how to pay; with big uncertainties about the availability of different charge plants and on-street charging. We think that if the Government are serious—and we know that you are—about rapidly increasing the take-up of ultra low emission vehicles, something needs to be done to make the world of those low emission vehicles easier for consumers.

The Bill takes the perspective of asking, “What are the things that may currently cause a consumer to think twice or just to think, ‘Not now’?” There is concern about range. Well, the auto companies are dealing with that, because the range of the vehicles is getting longer, but there is also concern about the complexity and ease of recharging, about whether a particular charge point will be available and working when someone pulls up, and about whether it will be the right sort for the vehicle that they have. If we are able to clarify those things and make them simpler, the market will be a lot more attractive.

[Mr Hayes]

Q I want to pick up a point that Mr Wong made about safety. Is it your estimation that there will be a graph, if you like, and that as vehicles become automated in part they will become safer, and as they become safer accidents will fall? We now have assisted parking, for example, and my wife tells me that that means I am less likely to bump the car, because I get a bit of help with reversing. Could we develop an understanding of a growing level of safety as a result of partial automation?

David Wong: The best way to answer that question is to look at what is already available today in terms of automation. We do not have autonomous vehicles yet, just to be clear—we are unlikely to have autonomous vehicles until around 2020 or 2021—but what we do have is increasing levels of automation. The best example to quote is autonomous emergency braking, which is essentially level 1 or level 2 technology, using SAE International’s definition. AEB has already been shown to have contributed to the reduction in real-world rear-end crashes by 38%.

[Mr Hayes]

How very interesting.

David Wong: That is an empirical study.

[Sir Oliver Letwin (West Dorset) (Con)]

Q We heard earlier from the insurance industry that they had been led to believe that autonomous vehicles, as they evolved and eventually came to market, would inevitably contain software that would enable the vehicle to reject a transfer from the driver to the autonomous system if it was in a location that made it unsafe for the autonomous system to operate. I am talking about the period during which we do not have cars without any steering wheels but we have ones that are sometimes autonomous and sometimes used by drivers. Do you share their confidence that vehicles will always be manufactured with software that prevents handover to the autonomous system except where it is totally safe?

David Wong: I think it is more likely to be the other way around. That is, it will be a question not of whether the system rejects a request from the driver to hand control over to the vehicle, but of whether the system serves up the offer of automation to the driver, given the right and safe conditions.

[Karl Turner]

Q Could I ask what the average cost is? Am I right to say £50,000?

Brian Madderson: It can be up to £50,000 per instalment. What has been happening is that certain companies have gone along and said, “Look, we will take over that cost but we want from you two parking bays for 30 years on a lease basis.” If you are thinking about 30 years, that is a very long time. It precludes you, as the owner of that freehold property, from perhaps expanding your shop or putting up a new car wash— indeed, from perhaps even selling the property to someone else. So most of them have opted away from that style of investment.

[Mr Hayes]

Q To jump back to your point, Brian—it is nice to see you again, by the way—you will know how supportive I am of small and medium-sized business of the kind you represent. Is it fair to say that the Bill begins a process of spreading the number of charging points by picking on and mandating those larger retailers, but that to get the coverage we all seek there will need to be other mechanisms, because in rural areas, for example, where many of you are based, there might be no large retailer conveniently situated? Can you see the Bill as a welcome start?

Brian Madderson: First, I do not agree at all with any form of mandating because this is interventionist by the Government in a market that is so new and in such a state of flux that there should not be mandating. This is a perfect example of where market conditions should encourage investors to invest in the product that is right for them at the time. Mandating may make them make a false decision, which would prove very costly and certainly not be beneficial for the consumer.

[Mr Hayes]

Q So Mr Wong thinks we should have a co-ordinated national strategy, whereas you think that the market should prevail. Is that the difference between you?

Brian Madderson: Yes, I think it is good to have a market strategy, but you would certainly need to have proper funding available to not only small retailers but large retailers as well. By this, I mean the independents, certainly. The big oil companies today count for relatively few of the total number of filling stations—less than 15%—across the UK.

[Graham P. Jones (Hyndburn) (Lab)]

Q Obviously, you represent the motor manufacturers, and I am concerned about the shape and size of vehicles going forward and the adequacy of the legislation. My hon. Friend the Member for Kingston upon Hull here has, I think, a Twingo—do you have a Twingo?

--- Later in debate ---

[Graham P. Jones]

Q It is not just that. What if I set off with a trailer in manual mode but I suddenly decide to be sneaky and switch it over to automated and go to sleep? There are a whole bunch of issues around the change in form, shape and size of vehicle and going between manual and automated.

Steve Gooding: I would say a similar thing as to Mr Efford: as a consumer, if I am being invited either to travel in one of these vehicles because it is the equivalent of private hire, or to buy one, I expect to buy something that has been certified as safe for the use to which it is going to be put. If it is inappropriate for me to hitch a trailer to it and use it in autonomous mode, that had better be made clear to me at the point when I buy it.

[Mr Hayes]

Q I have one further question, on a slightly different subject. This morning, we talked about how these developments will change the nature of the skills required. Steve 1, if I may call you that, mentioned that earlier. Presumably you will also acknowledge that it will give rise to new skills. There will be a shift in skills and new kinds of jobs and skills will develop. Is there not an exciting prospect of a whole range of new competences coming as a direct result of this technology? Is that fair?

Steve Nash: Absolutely, yes. There is probably more opportunity than threat from the new technologies. We are interested in ensuring that those skills develop in the right way. If you look at autonomous vehicles—I mentioned electric vehicles earlier—we only know as yet what manufacturers have said about their plans in the future. It may well be, for example, that when we get to level 5, or even level 4, a lot of those vehicles are not sold in the way that they are sold today. A new electric vehicle was launched a couple of weeks ago by a new brand called Polestar, which is owned by the same people who own Volvo. They say that the car will be sold on a subscription model, so it would remain within the possession of the manufacturer.

There is a lot of road to cover between now and then. Whoever is looking after those cars—I have already talked about electric cars, but when we get to autonomous cars as well—they will still have accidents. Things will drop on them and things will happen to them that are not caused by the car. When they are repaired, we have to be assured that they are repaired to a standard that returns them to exactly the same capability they had before the accident, which means we need people who are certifiably competent to do that. That is where we are interested in seeing some clarity.

We have cars with quite substantial autonomous capabilities already—Tesla is a good example—and I have seen second-hand examples of them that have gone beyond the dealer network. You have to wonder about the competence of the people who will work on that car—I am not saying that they are incompetent, but I do not know that they are competent. When someone next engages the autonomous capabilities of that car, will they do the things they are supposed to do? We cannot just leave that to chance. We have to be sure that there is some way of assuring ourselves about the people who work on them. This is not like the days when there was somebody who was “a bit handy”, as I think the phrase used to be, and you could give your car to them and they could look after it. This is a paradigm shift. We need to move with that and recognise that these cars, even though they have four wheels and look a bit like the cars that we have today, are entirely different. The skills base needs to be elevated to deal with them because they are an entirely different prospect.

[Rosie Duffield (Canterbury) (Lab)]

Q If there was one aspect of the Bill that members of the panel could change, what would it be?

Brian Madderson: The mandating of motorway service areas and large fuel retailers should be taken out at this stage because the market is just developing far too rapidly. We have even asked the Department for Transport what the definition of a large fuel retailer is, and it has said that it does not know yet and it will consult on that. Is it the size of the plot of a single one? Is it a multi-site organisation that might have filling stations all over the UK? Is it the amount of existing fossil fuel that a retailer is supplying? There is no definition, so I do not think it is reasonable or fair to mandate a large fuel retailer when you do not know what that is.

For similar reasons, I do not think that is fair and reasonable for motorway service areas either. There is just no money in it at the moment to justify huge investments, but there will be at some stage in the future and that is when the market will be able to say, “Let’s move on this now, and quickly too”. Hence my plea that the planning authorities are fully engaged to be able to allow effective planning applications as and when they are required for charge points.

Steve Gooding: Rather than changing something in the Bill, I think we would say that the powers—particularly in relation to electric vehicles—are drawn quite broadly. We would like to see how they are going to be used in succeeding regulations. We published some suggestions on how they might be crafted. There will obviously be some concerns—Brian’s perhaps first among them—about the implications for the operators of service areas, for local authorities and for householders. We would like to see the detail and to be confident—as I am sure we are—that the Department will get it right.

Brian Madderson: I would come back to that and say that the RAC’s report suggests that forecourts—filling stations, as they are at the moment—are probably one of the least best places to put a bank of charging points because of constrained space and alternative use, and because the few that we have today are all pretty busy selling diesel and petrol.

Steve Gooding: Apart from motorway service areas.

--- Later in debate ---

[Sir Oliver Letwin]

Q When do you anticipate results from those trials?

Suleman Alli: I believe within the next 12 to 24 months. We are looking abroad as well at other countries to see how we can generate learnings from those trials. Certainly, in the next 24 months we will start to see concrete evidence that we could present.

[Mr Hayes]

Q I wanted to bring up two or three things. The first is that you presumably agree with the changes we made from the first Bill, which was the forerunner of this Bill—the Bill that did not make the cut before the election. You will remember that what we have done this time is clarify the definition of automated vehicles, as a result of previous scrutiny. We have tightened that definition. How important do you think that is in providing confidence to the industry in respect of further developments?

Robert Evans: Automated vehicles are not strictly my area of operation, so I find that that is something that I cannot strictly answer.

Marcus Stewart: In some of the work that we have done when we have projected forward and looked at various energy scenarios, we see automated vehicles as having an impact on total energy usage. More automated vehicles, and clarity around the question, will allow different business models to come forward. Car sharing is more likely as part of that, and that will reduce the overall demand on the energy system, but we believe that it is still quite a long way out—maybe 2030-plus—before we start seeing any significant impact from that.

[Mr Hayes]

Q In terms of electric vehicles, I take it that the availability of a robust charging infrastructure is critical to the further take-up of those vehicles. I know there are other barriers to entry—market price, reliable battery technology and so on—but presumably in your view the charging infrastructure is an important part of encouraging more people to buy electric.

Robert Evans: Yes, absolutely. This is part of a process that the Government have played a key role in seeding—the introduction of charging in key locations and providing support to Plugged-in Places and now to the Go Ultra Low cities and others, to create exemplar projects and to encourage the roll-out of infrastructure. Making that infrastructure visible is a key part of reassuring people that owning an electric vehicle is a good thing. Being able to have a home charger, with support from the Government, that meets very high technical standards is also really important, so that people are not charging their electric vehicle from an extension cable or similar on a three-pin plug, which we would not advise.

The Government have played a very important part in dialogue with industry about the process of seeding. Now we are in a situation where we have more than 100,000 electric vehicles on the road, and the car industry is committing to introduce the vehicles, and so the roll-out of infrastructure is occurring largely with market forces, in the sense that businesses and locations are realising that they need to have charging as part of their offer. If it is a tourist destination, it wants to have electric vehicle drivers come to its location rather than another one, and so on.

We have good momentum, but it is still really important that where there is workplace charging, for example, we get conversion of people who work at that location because they see that there is charging that they could use, they start to think and then they buy electric vehicles. We thoroughly commend the Government’s workplace scheme, because we can see the catalytic effect that it is having.

[Mr Hayes]

Q Finally, we heard a lot earlier about the development of skills. The point was made across the Committee that we need a co-ordinated process by which we encourage the further development of relevant skills as the technology moves on. What is your thinking about that? Clearly, the industry is doing a lot of work on skills, but how can we more effectively accelerate the acquisition of the necessary skills so that we are not left in a situation where this technology can be serviced at only a very limited number of places?

Robert Evans: Skills is one of those challenging areas where we have a plethora of schemes. I was told that there are currently about 220 different skills initiatives for the motor industry. The challenge is not necessarily to create another skills initiative, but to work out how best to blend the relevant content into existing initiatives. Certainly on the garage side of the motor industry, greater skills or a spreading of skills for mechanics and engineers in terms of them being familiar with and able to operate on electric vehicles would be helpful. There is a general skills shortage in the motor industry, and that is something that training and development at a local level can assist.

[Mr Hayes]

Thank you.

[Iain Stewart (Milton Keynes South) (Con)]

Q Following up on the question asked by my right hon. Friend the Member for West Dorset, I have a question about the capacity of the grid to cope with the expected increase in demand, and in particular the timing of that demand. While researching for the Second Reading debate, I came across an Atkins report that draws on findings from the Energy Technology Institute that peak demand is likely to be in the early evenings—particularly Sunday evenings—and that that could increase demand on the grid by 10 GW, or 20%, at the time when it is least able to cope. Is that a finding that you recognise?

Marcus Stewart: One of the key things that affects the impact on the grid is people charging their cars. Smart charging is absolutely key to mitigating that. I will give you some examples from the work that we have published. We published our “Future Energy Scenarios” report in July. In a high-growth scenario that aligns with the Government’s target to ban sales of diesel and petrol engines in 2040, we would expect to see around 9 million electric vehicles in 2030. That would add something like 17% to peak demand, which occurs on a Monday or Tuesday evening in the winter, if there was not smart charging. If there was smart charging and people responded to that through time of use tariffs or other incentives, that could be reduced to around 6%. How people charge and how they are incentivised to do it has a real impact.

At the moment, the technology exists—the charging posts that have been put in have that technology—and we support the measures in the Bill to ensure that all charging points have that capability, which would make a significant difference to how easily electric vehicles are accommodated by the network nationally and locally. Smart charging is absolutely key, and we support the approach in the Bill.

--- Later in debate ---

[Scott Mann]

Q I have one small supplementary question, if I may. Do you see yourselves as being an end-to-end provider or do you see other companies coming in to fill that middle gap?

Marcus Stewart: From a national grid point of view, my role is to balance the network and ensure that the energy is balanced. We have a transmission owner part that would own the high voltage network, and certainly the element up to a connection. Anything beyond the connection is available for third party competition. Any service provider could put that in. A deregulated version of the National Grid or another third party could put that in. Our primary role is the reinforcement element upstream to support that.

[Mr Hayes]

Q On the back of that, between you there is immense expertise in managing complex systems—I have read your CVs. On the issue of grid management, earlier today we heard a call for some kind of co-ordinated approach on where charge points were located to ensure their spread, and to ensure that there were no areas that would become black holes where there were not enough charging points. Presumably, any such co-ordinated plan would need to be married to the supply of electricity via the grid. The Bill does not yet do this. It is a first step down this road, and it simply increases the number of charging points. Do you see the sense of putting together a co-ordinated national strategy that ties together the provision of the charging points with the provision of the power?

Marcus Stewart: I think it would have some merits. I am not sure whether it needs to be mandated or not.

[Mr Hayes]

Q I was not necessarily suggesting that it ought to be mandated; I was simply arguing that it might be facilitated. There could be a co-ordinated approach that might facilitate—this is the word that was used earlier—both the provision of charging points and the other considerations.

Marcus Stewart: It certainly makes sense to look at where there is good capability on the local or national network, and to consider that in respect of good accessibility for people; for them to be able to come in, connect and charge up their cars. I would expect those to be offering the early take-up points. Effectively there would be a least cost route to getting fast charging points delivered, in particular. A number of parties would have to come together and look at those opportunities: the National Grid, local network operators, charge point owners, service station owners and people like that. That would make sense.

[Matt Western]

Q I was interested in what you were saying about the workplace uptake, the conversion and how it switches people. Do you think we are doing enough—with all the housing developments and the local plans being put in place across the country—either to mandate or to encourage a rapid and widespread adoption of electric vehicles?

Robert Evans: The answer is no. We are not doing enough.

--- Later in debate ---

[Rosie Duffield]

Q You talked about getting drivers behind this because they know it is the right thing to do, and that drivers are frightened. We are also trying to meet the environmental targets that the Government have set. Knowing car enthusiasts as you do, do you think that people will ever feel as enthusiastic and fanatical about electric vehicles as they do about Ferraris or other exciting cars?

Quentin Willson: That group of car enthusiasts is quite small now. It is a very small percentage of the market. Most of us just see the grim business of getting from A to B as a necessity. As I said earlier, the idea of the open road with your Porsche 911 is a golden age that has passed. The Tesla P100D is the fastest accelerating car in the world. It does nought to 60 in 2.4 seconds. It is faster than a Ferrari, which is great. But in terms of mainstream electric cars, I think it will be a while before your hardcore car enthusiast really likes them. We have a big Clarksonesque blockage here—he does not like electric cars or the people who drive them—but I think he is an irrelevance and so are those car enthusiasts.

Our concern should be mainstream consumers who have to get to work, to school, to the shops and to hospitals. We have to make it easy, effective and inexpensive for them but also give them that range. Until we get rid of range anxiety through better infrastructure and battery technology, that will not happen. What will happen is that they will buy hybrids that will do 20 or 30 miles on electric but the rest on petrol. That does not really solve the problem, does it? The people in the Mitsubishi Outlanders who hog all the charging stations will do maybe 20 miles on electricity and the rest on petrol. Again, that is something we need to manage. We need to look at the far reaching, perhaps unintended, consequences of the decisions that we are making now.

[Mr Hayes]

Q Thank you for coming again; you will remember that we had an exchange when you came to the evidence session on the previous Bill. One would accept your view that we will not switch to electric vehicles overnight. Clearly, we do not want to eliminate the use of older classic vintage vehicles—my right hon. Friend the Member for East Yorkshire challenged me on that on Second Reading—but surely there is a good case for taking advantage of the improved battery technology, the greater affordability of electric cars as volume grows, the smoother ride that they give, and their many other virtues. I do not claim that electric cars are nirvana, but given that this will not happen just like that and some allowance will need to be made for the older vehicles that my right hon. Friend champions, surely you acknowledge that it is likely to happen and in the end it is quite a good thing?

Quentin Willson: I agree. The older classic cars are a tiny proportion and their emissions are a raindrop echoing in an ocean because they are used so seldom—some for only 200 miles a year. We should not worry about them.

Mass electrification is coming, but until I see a step change in battery technology, we will not be able to give consumers the beatific vision of 300 to 350 miles to one 40-minute charge. Will that come by 2040? I do not know. You have heard from the car manufacturers. Will we be able to accelerate that technology? It is good that the Secretary of State for Environment, Food and Rural Affairs has given the 2040 cut-off date, because up to now they have broadly been compliance cars made to keep emissions down for EU regulations. Manufacturers will be throwing everything they can at developing batteries, but someone like Jaguar Land Rover does not really have any electric product at all, and Mini has only just scrambled together one electric Mini that does not have a brilliant range. They have a lot of work to do to get to that level. It has taken us 100 years to get to the efficiency of the combustion engine as we have it now. I know innovation is not linear and it will start to climb up, but we need to understand that if we do not give consumers that 300 to 350 mile range, it is going to be very difficult. You see Teslas strolling down the motorways, because they do 250 miles to one charge. That is great, but you never see a Nissan Leaf—think about it.

[Mr Hayes]

Q Let us follow the logic of your argument. I agree the battery technology is a key determinant of take-up, as you described. Clearly, capital prices are a big issue too, and we have supported that over some time, but we acknowledge that until we get volumes up, prices are unlikely to fall significantly, in the way you describe. The third thing is the charging infrastructure. Confidence about being able to recharge on long journeys is critical to people’s acceptance of the technology. We have agreed that the move to electric is rather a good thing and we excluded the tiny number of vintage vehicles and classics. Do you acknowledge that the Bill is at least a step towards that? It begins to put together a framework of legislation when it takes account of infrastructure that will at least deal with one of our three shared perceptions about barriers to entry.

Quentin Willson: Completely. We have a lot more consumer awareness to do. I will be doing events with a shopping centre group across the country where we have consumers coming and they have test drives of all these electric cars, plus everything you ever wanted to know about electric cars but never dared to ask, on stage. Go Ultra Low and OLEV do great work; I think we could do even more, but we could also incentivise universities to come up with technology. Danny Alexander and I talked about a battery prize of £10 million. Let us make it £50 million for the real world-class development of a battery that is lightweight and not dependent on rare earth metals. Half the cobalt in the world is in the Democratic Republic of Congo—that terrifies me.

If you can come up with the technology that creates this new, wonderful, miracle battery, then we lead the world and a lot of these problems just disappear, but we need to accelerate that process. The two things—the infrastructure and the battery technology—really need to run, because at the moment we are running too fast with this, because the technology is lagging behind. It is absolutely laudable that we do what we do and put the legislation in place and prepare consumers, but we have to make sure that that technology can support long journeys.

I am afraid you cannot expect consumers just to charge at home at night. They cannot do it. They will want to make journeys. This morning I got into my Nissan Leaf; I had 80 miles on the charge after an overnight charge. It was cold, so I had to defrost the windscreen and put the heater on. I took my daughter to school. The charge went down to 55 miles. If I wanted to go anywhere else, I would have to stop at the end of the 55 miles and charge for 40 minutes, if I could find a rapid charger. If I could not, I would have to do two or three hours. Realistically, we cannot expect consumers to do this in the short to medium term.

[The Chair]

Thank you very much for your evidence, Mr Willson. As the owner of a beloved 25 year-old BMW, I am grateful that classic cars have a future. Sir Greg Knight will be even more grateful as he is the owner of several vintage cars.

Examination of Witnesses

Denis Naberezhnykh and Stan Boland gave evidence.

--- Later in debate ---

[Sir Oliver Letwin]

Q It is basically like not being able to get a cab.

Stan Boland: If you like, yes. We think there will in any case be remote supervision so that it would be possible for a control centre to be able to monitor any cars that are stopped and then perhaps carefully move them to some other place. We are expecting a remote control room with perhaps one per 30 cars or something that would be able to take over and carefully manage the car. We are also expecting the cars to have a limp-home system, so if there is a catastrophic failure there would be a limited amount of capability where the vehicles could—at quite a low speed and with warnings—find their way back to a service centre.

[Mr Hayes]

Q I have three questions. First, you made an interesting case in response to questions from my right hon. Friend the Member for West Dorset and the hon. Member for Eltham about what you see as the likely development in autonomous vehicles. I will put two scenarios to you, and I would ask you to describe the most likely one. There is an instinctive, intuitive view that autonomy will grow gradually, partly because that is more likely to lead to public acceptance. So rather in the way that assisted parking or sat nav or cruise control have become increasingly routine, other aspects of autonomy will be added to that. Autonomous vehicles will sort of creep on us.

There is another view that we may go straight to a kind of autonomous vehicle. Indeed I have looked at some of the R and D on that. As you may know, there is an entirely autonomous vehicle at Greenwich supported by Greenwich council, with some Government funding too. That is a vehicle that travels on a straight run of road that is entirely autonomous. You get into it, and it does what it says on the tin. Which of the two scenarios is the most likely, in your view? Or are they most likely to develop in parallel?

Stan Boland: They are developing in parallel today, so I think that is the state of affairs. The first of those can be characterised as the view of the German car industry, which is that these things will happen, but in 2035 or 2040. In the meantime we can just keep adding these features, keep selling people more features, and keep selling cars that people buy. However, I think the world was really shaken up by the challenges we saw in the 2000s and the emergency of Google cars and so on, as well as the idea that it was within touching distance for science to deliver fully autonomous capability in a relatively meaningful timeframe.

That really is the difference between level 2 and level 3 autonomy and what is really a huge jump to level 4 and level 5. Our entire business is predicated on level 4 and level 5 being the dominant model. We think that that is the dominant model for getting to a situation of safety in an urban environment. Significant amounts of algorithms, computer models, training data and sensors are involved in achieving this, which will considerably increase the cost of the car. We estimate that getting the car to human levels of safety will add a further £30,000 to £40,000 to its cost. That is not a car that people buy. That is definitely a service, and if it is a service then it is fully autonomous.

[Mr Hayes]

Q My second question is about software. We debated this to some degree today. Presumably, the challenge is to develop sufficiently sophisticated software to anticipate scenarios encompassing all kinds of different eventualities. An interesting question was put earlier by the hon. Member for Eltham about the element of human judgment in driving when faced with a dilemma, where you would hit traffic rather than a child, or you might swerve and possibly cause a more serious accident. The way that scenario planning is written into software would require hundreds of thousands of scenarios being tested. I know there is R and D being undertaken in this area. Would you briefly describe that to us?

Stan Boland: It is impossible to test all of that in the real world, and it would not be safe to do so. It has to be done as a simulation, which is the key to getting to the point where we have safe systems that can operate in our cities. We have to be able to simulate all the sensors on the car and all the different failure modes and so on. We have to simulate all the cases where our predicted models break down, or where somebody in the distance who is wearing a green pullover against a green wall with a reflective window near it cannot, for whatever reason, be seen in our systems. We have to be able to simulate those kinds of things—perception failures. We also have to simulate the extent to which we may not be able to predict human behaviours. We may never have seen a particular behavioural type before, and it may be dissimilar to anything we have seen before.

We have to do all that in simulations, so the money is invested in creating a simulated world that may be like the whole of London, photo-accurate for example, and it may be that we create generative models that allow us to create every angle of a road—instead of 43 degrees, it is 44, 45 or 46. Instead of five objects, there are six; instead of a certain kind of road markings, they are slightly different. We can basically generate all that in simulations, so we can drive potentially billions of miles in simulation ahead of that software actually going in a vehicle and being sent out on the road. That is the way we can really assure the safety of those vehicles—a heavy investment in simulation. It turns out that the UK is good at that. The UK is good at artificial intelligence, gaming and simulation, so we are in a good position to do that.

Q So you are not simulating what is, as I put it, a tens of thousands scenario; it is millions. It is the whole of London, in all weather conditions, in all circumstances, for all vehicles, in all eventualities.

Stan Boland: Exactly. We will find real cases in the real world which we will codify. We are working with TRL to do that, to deliver a curated set of regression test cases.

[Mr Hayes]

Q Thank you for that; that was fascinating. My final question is about skills. We debated skills earlier; Mr Turner raised the issue and I then amplified it. From what you are describing, and I discovered this in my early research, the car mechanic of the future will be a software engineer as much as he is a mechanic, and that is going to require a step change in skills. Are we ready for that, and if not, what are we going to do about it?

[The Chair]

We will have to have Ministers with proper skills in future too. Sorry, Mr Boland, please answer the question—that was just a facetious remark. This must be the last answer, because we might have multiple Divisions.

Stan Boland: We definitely need more software engineers as a nation anyway, so we are probably not ready for any of this in terms of the total number of skills that we need to go alongside companies the size of Silicon Valley companies, but I think there is a kind of rarity about what—[Interruption.]
