I honestly think that even when we do get full self driving cars, you won’t be able to own one. They will be rideshare only. The reality is that autonomous vehicles are so complex that you need advanced mapping of very well known conditions to make this feasible. Companies will make these sort of maps for major cities where they run their ride service but anywhere else cars will just not be advanced enough to handle unexpected conditions. Self driving cars will only ever work under controlled circumstances such as well known cities and suburbs.
It is also the case that the downtown area of cities is often the place where parking your own car is the most problematic, so being able to use a self-driving rideshare would be really helpful for that reason also.
