I don't know if you've seen Elon's last announcement, but that is basically exactly what Tesla is planning to do with the Model 3. Sell the car and let people loan it out to an autonomous fleet with the app. Tesla would also have its own fleet for cities without enough Tesla owners. This would allow people who could otherwise not afford a 35k electric car (before incentives) to buy one and is the reason he doesn't think it'll be necessary to build another cheaper version.
