The biggest cost in a vehicle is the depreciation that comes from both time and wear. Cars that serve as taxis wear out 10x faster than commute cars. Why would I want my car to wear out faster? (And electric cars wear on the battery, whereas gas has direct fuel cost.) Also, when the car goes home to serve the family, that means the family owns only one car -- clearing out at least one parking space compared to two active cars. Finally, if I go shopping today, I have to circle a number of times just to find parking. Driverless cars that know where spots are, and don't care about walking distance, can get of the road faster than that. So... I'm sure we'll find new problems, but that seems unlikely to be one.
