Vehicle Technology and Aviation Bill

Debate between Alan Brown and John Pugh

2nd reading: House of Commons & Carry-over motion: House of Commons & Programme motion: House of Commons & Ways and Means resolution: House of Commons
Monday 6th March 2017 Commons Chamber

[John Pugh]

I am presenting my personal observations. The hon. Gentleman has acknowledged that there are problems and I am simply alluding to them.

[Alan Brown]

Did the hon. Gentleman not make the case for autonomous vehicles when he talked about people potentially making long-distance journeys when they are tired? The whole problem with drivers at the moment is that they fall asleep at the wheel and lose concentration. Autonomous vehicles must be an improvement on that.

[John Pugh]

We are just looking at different sides of the same problems. It is quite obvious that people will not get tired in autonomous vehicles in the same way, but they will then perhaps make longer journeys than they otherwise might have. Both points remain valid.

If people are going to go along the motorways in convoy and at the right speed all the time, have we not considered the thought that everybody could get into the same vehicle? Have we not, through a back door, invented the bus all over again?

There are imponderables from a manufacturers’ side. It is easy enough to insist on technology that does not let people drive if it is unsafe, but once they are on the road, vehicle failure midstream is always a possibility, even if the software is up to date. There might be unexpected damage to sensors or equipment because of conditions such as bad weather or through accidental damage. In responding to a change of circumstance mid-journey, at what point is it the driver’s responsibility? If road signals fail, road markings are obscured or traffic is unexpectedly redirected in a haphazard fashion, at what point does the manufacturer, the council or the passenger take the blame should an accident occur?

We can leave out all the hypothetical moral dilemmas involving nuns or how a vehicle would distinguish between a black bin bag waving and a child frozen in terror when collision is inevitable. Machines would make different calculations, and I am sure there would be solutions. I suspect that with the development of artificial intelligence, machines will better reflect our moral preferences and become smarter. The other day, I was torturing myself by thinking about what would happen if two autonomous vehicles met on a single road, on which one could not pass the other, and one had to give way but both systems predicted that the other would. One would have a sort of parallel to the Balaam’s ass dilemma.

The Bill is a modest attempt to tackle the issues I have outlined. The pious hope behind it is that the tricky issues will eventually be ironed out in court. But courts can operate only within the law they have, and my expectation is that technology will move faster than the law and we will be back here soon.
