Robocars - Autonomous Drive, Self-driving, Driver-less cars

Cars are ownd for a multitude of reasons. See Top Gear for some examples . They won't change that

I suspect they are equally likely to disrupt local public transport systems. I am not sure that's a good thing.

Emphasis on multitude. Top gear is as far removed from an indicator of the main reason of driving as there is. In the grand scheme of things, for most people, the car is transport from A - B. No one is saying Autocars are going to replace everything else at once.

Which answers your second comment. If driverless cars are all round better, faster, cheaper and more efficient transport system for everyone, not just those that can afford it. Would you not rather use that?
