"Personal rapid transit is just a waste. You can transport A LOT of people by rail ... orders of magnitudes of people more than cars"
You're answering a question no one is asking. Cars and taxis (and imagined self-driving cars) get people from where they are to where they want to go. Roads are capable of serving any trip, and with a reasonable travel time. If transit could serve most trips then transit could be successful. Start from there, and see if you can work backwards to traditional rail mass transit. I don't see it happening, but maybe I'm missing something.
