True. But you are talking about logic, which seldom matches human behavior. Humans are driven by other matters besides efficiency. A car is a status symbol. This must be taken into account when advocating solutions that may transmit a lower status for its user, be it driverless cars, on-demand cars or something else. Ignoring it is futile because this is above all else what made cars so widespread. No other fact explains why some people have more than one car strongly than this. Take the Segway, a wonderful device with much going for it except you looked stupid while riding it. It was a perceived low-status symbol and it failed because of that.
