In a world of automated vehicles, people wouldn't need to own their own cars. That will be, in fact, the more expensive option. If I rely on automated cabs instead of owning a car, I only pay a small part of the capital cost of that car. I also don't need a garage for it. Or a parking spot for it at work. And I can much more easily rent only the amount of car that I need at the time, which is not much when I am just going to work by myself. The total number of cars goes down. The average size of cars goes down. The number of empty seats goes down.
