We do not agree about everything, Christian Wolmar and I, but on driverless cars we do. Myself, I have long been a driverless cars sceptic and have earned many patronising putdowns from people high on the hype cycle. Graham Dalton, then head of the Highways Agency, was amongst them. “You don’t understand, George. They will be here sooner than you think,” etc., etc. Of course it depends what “be here” means. If it means driving in test conditions on well controlled roads in good visibility, then fine.
