You mean like last time? More cars being the answer to problems created by creating too many cars and reasons to use them is like more people buying guns to counter the gun problem, and I can't think of better "tragedy of the commons" applicable situations.

As I start to get older and I spend less and less of my time in the deep suburbs, I'm starting to be more aware now of the phenomenon for people to get less social and less trusting the further away from a core area (or, arguably also the ground in the case of skyscrapers, but much less so) they live. I don't think it would be a net win to hypothetically encourage further dispersement from one another.
