The death of the auto has a lot of factors involved in it. Rising fuel costs, auto prices that are too high for average folks to invest in them, counterculture stuff that disdains the auto and the world designed for it, the sheer number of them that has caused both congestion and the lack of places to put them when we are not using them. In any contest in SF to get within 4 miles I can beat a car by using my bike every time.
