On-demand AVs will probably kill mass transit in the US. The poor will get the equivalent of EBT cards to ride, so there will be a social aspect to it. But framing it as some kind of Randian triumph ignores that there are places in the world where mass transit is very efficient because the cities are different. Private cars will be for the rich and should be taxed appropriately. Meeting your fellow citizen while riding an AV mini-bus will open your eyes to social diversity.
