Automated Vehicles Bill [HL]

Lord Holmes of Richmond Excerpts

Committee stage
Wednesday 10th January 2024 Lords Chamber

[Baroness Brown of Cambridge (CB)]

My Lords, I will make a comment on Amendment 1, but perhaps also a more general comment on some of the amendments in this group and the next. I absolutely recognise that these automated driving systems need to be accepted by the public, and I see that many of the amendments look to do that by increasing the emphasis on ensuring safety. I am sure that we are all hugely sympathetic to that, so I am very sympathetic to the motivation for many of the amendments—but we need to be a bit careful. This is a new area of technology—it is still developing, of course—and there may be some unintended consequences of some of the changes that people are proposing.

In talking about this, I will briefly refer to some recent research by Konstantinos Mattas and his colleagues from the European Joint Research Centre in Ispra in Italy. For example, in Amendment 1 we are asked to include a phrase about

“substantial real testing on roads”.

I think we really need to explore the value of this. Human drivers have a frequency of fatal crashes of one every 3.4 million hours, which would imply continuous driving for 380 years. To demonstrate that automated vehicles are safer than humans, you would need to run 100 automated vehicles for 24 hours a day for 225 years. Of course, if you change the software or the hardware, you might well need to repeat tests of this length. We need to recognise the challenge of demonstrating safety by long periods of testing on roads. The vehicles will have to be significantly unsafe for a realistic period of testing to start to show up the problems.

I cannot support Amendment 1, even though I hugely sympathise with it, because it is an apparently simple ask but I do not think it is likely to deliver the benefits intended. Unfortunately, it could be counterproductive, so I think the wording of the Bill as it stands is preferable to the proposal in Amendment 1.

[Lord Holmes of Richmond (Con)]

My Lords, I will speak to Amendment 55C in my name in this group and apologise to the noble Baroness who moved the initial amendment. I was just sitting down when she started to speak, so I apologise for not being fully in my seat. I declare my technology interest as adviser to Boston Ltd.

What we are talking about here with autonomous vehicles is really mobility enabled through technology. My Amendment 55C seeks to take some of the themes that have already been spoken to, not least by my noble friend Lord Lucas: the sense of how technologies are able to interact and communicate with one another—what we call interoperability. Interoperability should be a golden thread running through many sections, because it is critical to the success of these technologies.

There are extraordinary economic, environmental, decongestion and safety benefits to potentially be gained through the mass deployment of automated autonomous vehicles, but they will be gained only if the systems are interoperable with one other, so all the vehicles can speak to one another and to the transport control centres and emergency services control centres. Only through having that key golden thread of inter- operability will we enable the economic, environmental, social, safety and accessibility benefits. That is what my Amendment 55C is all about, and I look forward to my noble friend the Minister responding in due course.

[Baroness Randerson (LD)]

My Lords, I am pleased to take part in this debate, first to support the amendments in the name of my noble friend Lady Bowles. I will also speak to Amendments 22 and 43 in my name.

My noble friend has raised some important issues about the adequacy of simulation as a way of establishing the safety of automated vehicles. Cycling UK, in its briefing to some of us, has raised similar issues in the context of the more vulnerable road users. Experience in the USA—very definite real-life experience, especially in San Francisco—has revealed that there is no substitute for real-life testing and that permission to operate on real roads can be given too easily.

We all know that how we drive is based on the skills we have learned and the experience we have developed as human beings. I have no doubt that a vehicle driving itself will in some ways be a lot less vulnerable than we are to feeling sleepy, losing concentration and so on. But it is a very complex thing to simulate and build something that, for example, notices that the gentleman ahead, who has a white stick, will therefore be blind or very poorly sighted. It is difficult for a simulation to tell the difference between the hesitation by the side of the road of an elderly person who is looking anxiously around and that of someone who is hesitating because they are reading their phone at the same time, or to notice that someone who has just stepped off the pavement is a teenager who was having a joke with his mates 10 seconds before and may not be concentrating. These are all things that we notice every day and make a judgment on; we see potential issues that we may have to take into account.

I am sure that simulating all that can be done, but it is the real-life, real-road experience that needs to be taken into account—the subtle messages. It is difficult to imagine a road system much more complex than that in the UK, with its bendy roads that are heavily trafficked and a high number of pedestrians. I was recently in the USA, where I was immediately struck, as I looked down from the air, by the regularity of the grid system. When I got into towns and cities, I was struck by the very low number of pedestrians in the streets compared with Britain. We have a much more complex and unpredictable set of circumstances.

My Amendment 22 refers to the checks and permissions that will be required before foreign vehicles are allowed on UK roads. Foreign vehicles drive on our roads all the time, but it will be much more complex in future. At the moment, we rely on the fact that foreign vehicles have had permission in their own country and are deemed to be satisfactory for their own country, and that the driver, if they have come from abroad, will be adapting—some much better than others, obviously. We rely on that awareness and adaptation. The cars, vehicles, vans and HGVs concerned will have to download a whole new lot of software, because every perception of the vehicle—all the distance, width and so on—will have to be done from a different point of view. They will have to download the map of the whole UK that these vehicles will operate on. Some of our road signs are different from those in other countries, so awareness of them will be a more complex issue.
