Nice post, I went over and commented. :) I agree with shortroadto, we can end up in a endless cycle where we build a highway, people move further away, requiring the highway to be expanded which starts the cycle again. It ends up wasting a lot of resources. I don't think that cars are destroying our lives, but some adjustments need to be made. Unfortunately, a lot of the problems are political. You can't just go and slap tolls on roads to more fairly price usage, because people will revolt against that.
