> No, the picture demonstrates why cars are bad; they require too much space. Cars take more space, but not nearly as much more space as that picture tries to imply. It shows a single bus with full capacity, but one car per passenger. If it treated cars equally with buses, there would be significantly fewer cars, smaller cars, or many more busses. You can have a smooth, 60 mph ride through San Francisco, or you can have enough stops and capacity to serve the entire city. You won't have both. I've heard promises of rail for 40 years and maglev for 20. I think they can be very useful, but they won't serve all the needs of an entire city, much less an entire metropolitan area. Cars and future car analogs will probably always be necessary, and a public system which uses them could be very helpful and both save and free up a lot of space. But this is about a lot more than just space.
