His personal possession is still taking up a vast area of a public space While true during the time the car is transporting a person, self-driving-cars-as-a-service requires fewer cars in total, and need not be parked near the destination (or at all during high-use periods). Many US cities came in to existence or experienced major growth during the age of the car. They are built for people with cars, and would be quite difficult to convert to an effective public transit system. Consider Jacksonville, FL as an example. It has a population of less than a million and it's sixty miles wide. It wouldn't be terribly hard to make a strong case for building new cities differently, but causing Jacksonville to have a usable local rail system would be considerably more expensive than deploying self-driving cars there.
