Your last point is I think what has the potential to change things here. > i reckon "everyone needs their own car" is nonsense Once cars are self-driving the need to own more than one (if any) is vastly reduced. A family could easily share one car if it can drop everyone off at work and still be available for use mid-day. It looks like Uber is betting on the future being one where even those who own a self-driving car would be hiring it out during times of low-usage. Why own a car when you can summon a driverless one at any point? Similarly we could see a large decrease in the need for at-work and on-street parking if a car can take itself off home. Perhaps there might be a rise in commercial car-parks scattered around a city where a car can retire to safety and for a charge while it awaits its next job. A clever car could pick the most efficient of those to be ready for all users. The biggest concern I have about the rise of the electric car is that we are currently doing little about the cleanliness & CO2 emissions of our electricity generation. Clean/safe nuclear power can't come quickly enough.
