I'm all for driverless transportation, but let's face some important facts.
Why didn't we _already_ remove the drivers on trains? The train/metro system is basically a closed system which is much easier to control than a car in traffic. This is a genuine question: why? It looks like a much easier to solve problem.
Second problem will be certainly be fuel. A 20x increase in utilization means at least a 20x increase in fuel, unless the car is _transporting_ something at all times (which basically means car sharing). Sending your car home empty is crazy in terms of fuel.
Legislation is also going to be a hell of a problem, at least in EU.
