> There are more things to solve than just "the least amount of pollution and space." The argument I was responding to was that self-driving cars would be sufficiently more efficient users of space that it would obviate the need for public transport. This was demonstrably false. > But now you're punishing passengers that start a shift at noon. Sure, but (a) that's a financial question, not a capacity question and (b) rush hour is when both finance and capacity collide. Public transport is a more efficient option per passenger-kilometre and per square metre of road or cubic metre of tunnel than self-driving cars. It is always going to be. Self-driving cars will have other virtues and will reshape transportation, but ascribing magical powers to them does nobody any good, especially if it leads to defunding of subways and buses.
