Automated and Electric Vehicles Bill (Second sitting)

Debate between Stephen Kerr and Craig Tracey

Committee Debate: 2nd sitting: House of Commons

Q My question is: if one of those conditions is not met, then you said that it will invite the driver to take back control. What happens if the driver either does not or cannot take back control? How quickly would that process need to happen? Given that, why does that not give the potential for there to be more accidents in the short term?

David Wong: In the first place, the limiting conditions are such that the vehicle can only operate under the traffic jam pilot functionality at 38 mph, so that is a relatively low speed. If the driver is required to take back control at that low speed, Audi has said that there will be a minimum period of 10 seconds for the hand back to take place at 38 mph. This is completely different from some of the things that may have been heard in the press, where people were saying, “Oh, at 70 mph there is a three to five second hand back, it’s impossible to do that.” It is perhaps impossible. Audi will have a minimum hand back period of 10 seconds at 38 mph.

If the driver still fails to react within those 10 seconds, then a minimum risk manoeuvre will be performed whereby the car will slow down and grind to a halt in the lane safely, flashing the emergency indicators and strapping the seatbelt tight across the driver. The driver might have passed out, or may have become incapacitated. That is the assumption. In the intervening period, there would be a series of warnings within those 10 seconds including visual, acoustic and eventually haptic warnings. So there will be lots of measures that Audi has in fact built in. In any case it is travelling at 38 mph, so it is perfectly possible for the car to gradually grind to a halt in the lane with those measures in place.

Steve Gooding: Some of us are entirely unpersuaded that level 3 makes any sense at all. I accept all of the reassurances set out by David, but you should consider for a moment the Department for Transport’s own research showing that you are much more likely to kill someone when travelling at 30 mph than at 20 mph. I wonder if, at 38 mph, the window being created by Audi in which its system can operate is going to be too narrow. I am not sure that I have ever seen a dual carriageway in an urban area that is free-flowing with clear signs in this country. I think, personally, that we ought to say that level 3 is something that we do not want.

Q In connection with what has been discussed today in relation to these five levels from manual to automated: in the context of the Bill, is the definition of “automated” in the Bill adequate for the purposes of the Bill at this point?

David Wong: We are informed that the policy intent behind the Bill is to do with the new insurance framework —the single insurer model framework—to cover level 4 and above. Insofar as that is reflected in the spirit and letter of the Bill, then that is adequate because it is at level four that the human being is—technically speaking—out of the loop, to use engineering parlance. The human being has surrendered control to the vehicle. At anything below level 4, the human being is still technically responsible and in the loop. So for these purposes the Bill is adequate.
