Well, then there's car insurance and gas. Despite being a huge fan of public transit, I actually think the efficiency numbers would probably still come out in favor of cars, in America, in the near term. Our country has been car focused for a hundred years and the assumption of car travel is baked into the way our cities (and especially suburbs) are designed. There would need to be years of shifting urban planning before mass transit really won everywhere.
