Why? You think we should be moving around in open air? Or you think we should all be moving though high density channels like trains? I don't see what's wrong with cars if they are minimally heavy, aerodynamic, and managed as a fleet. Busses are certainly not better. And trains only solve half of the problem. (Thoroughfares.)
