Luckily, I don't live in a place like this, but stories are emerging of more and more kids aimlessly hanging out in the suburbs (even more than usual). Recent legal changes and the poor economy have made it harder and harder for kids or their parents to support that second or third car.
Generally, this is all good, except that they live in places where driving is needed for almost all mobility. Where, all this will lead is anyone's guess but a deep transformative moment may be at hand. The sidewalks and corner stores people traded for a bigger TV room might be looking pretty good right now.
