> * Every tried crossing a NASCAR raceway on foot? This is one of the interesting advantages a public transit system has over a self-driving fleet of cars (which, incidentally, I also look forward to). Mass transit depends on the concept of "stops" or "stations". The way people get between destinations (like their home, the shop, etc.) and the transit station is largely by walking. Thus, mass transit necessarily builds in pedestrian friendliness. This isn't true for cars, which do not have such nexi. (Indeed, this lack is generally agreed to be an advantage.) This means that such designs will have to deliberately include pedestrian friendliness in order to have it, rather than being forced into it by the facts of the design requirements. I'm not saying it's a sufficient advantage for one or the other, but it's a definite thing.
