A couple of quick points: 1. Autonomous vehicles are going to drive down the cost of essentially hailing a taxi to the point that it will become an affordable alternative. What we need to do is make it so painful to drive yourself to desirable areas that you basically don't do it. 2. You keep going back to the suburbs, but we've mostly moved past that.

I'm not advocating to seriously create a mixed use development neighborhood in the suburbs. You'd have to demolish the whole thing probably.
