My Lords, I first declare my interest as an officer of the APPG for Self-Driving Vehicles and a business lifetime spent in the vehicle industry. I am also the father of a son who has learning difficulties and could, like many disabled people, certainly benefit from these vehicles. I have also been the chairman of the Greenwich trial technical committee. I can reassure the noble Lord, Lord Cameron, that the pedestrian schoolchildren in that trial who thought it would be useful to leap out in front of an autonomous vehicle to see whether it stopped tried it two or three times and found that it did stop. After that, they found the whole experience extremely boring and stopped taunting the vehicle in this way—so in fact it was perfectly safe.
This is an enabling Bill, to enable what I hope is a great industry. We cannot be certain about the future, of course, but we can be fairly certain about the present. The present state of cars cannot be optimum. They are driven badly by humans who get bored, smoke, chat or argue with their family, get drunk and certainly produce urban pollution by accelerating too fast and braking too hard. Computers will be better drivers because they have more varied input than humans, and much better ability to concentrate on the problems. The question of the moment is: when did you last enjoy driving? Was it when there was less traffic and when there were fewer bicycles and bus lanes? Would we enjoy driving more in an autonomous vehicle? This Bill is quite wide in its power to demand information. The danger is only that too much information is delivered. If the department gets terabytes of data following an accident, will it realistically be able to cope?
There are people working on digital commentary systems, which tell the listener what is being observed and why the vehicle is doing something. The systems are analogous to the way of teaching a young driver to improve by getting them to comment on their driving decisions. How much useful information comes out will depend on the detailed decision process, but it certainly can be considered. The alternative is that, following an accident, somebody issues terabytes of data and we are no further forward in working out how to stop other vehicles with other systems repeating the accident. That happens now, because human drivers are very fallible in remembering their own faults. In general, the sooner we can get this Bill into law, the better.
