The problem is that most people need their cars at the same time - rush hour.

  1. Optimized traffic flow that driverless gives you would be able to pack more vehicles on the road. 2. If we are treating all cars are like a fleet of autonomous taxis, it doesn't seem really crazy that you could also optimize carpooling where the car picks up other passengers to optimize the trip with respect to where you and they are going.

    Yes, you could probably share cars to a greater extent than we do today, but not nearly enough to get the ~20x reduction in the number of cars on the road that the parent suggested. If you have optimized traffic, you could live further out and the commute wouldn't take any longer, so that could lead to more sprawl. You also would be able to do something while commuting besides watch the road, making the commute more tolerable, which could lead to even more sprawl.
