> I would rather focus our efforts on improved density We can and should do both. When density increases smaller electrical vehicles, some entirely charged by solar on their roof, become practical. They are much lighter, use a lot less resources than a standard car, travel somewhat slower and generally ameliorate car problems, while being just as practical: usable in all weather, having cargo carrying capacity. Bikes and walking will always have these sorts of limitations.
