I'm not one who thinks the technology will ever really work in the way that some
urbanists think it will work, but I could be wrong about that. What I'm not wrong about is the fact that we still face the peak driver/commuting problem. As long as most people essentially need a car for their daily commute, driverless cars won't really remake the world. You'll still need a one car per commuter fleet. Those fleets could be put to work doing other things in non-peak times, but the peak need will still be there. They'll just be a slightly better carshare or possibly slightly cheaper taxi for non-commuting trips.
