Some people will still want to own a car, some won't. However, parking is going to be a lot less of a problem. 1. Some people will used shared ride services, so the shared car rarely needs to park. 2. Cars will be able to much more densely park. Autonomous cars that can communicate with each other can pack themselves in on the side of the street bumper to bumper. In parking lots with rows, spaces can be much narrower since people don't need to open the doors, the car can just pull forward itself. Even the rows between cars can be filled up. You see this at the facebook campus now because they don't have enough parking, but it takes an army of valets to move all the cars around. 3. People will own and drive smaller cars on average. Even for people who do own a car, the ability to have a larger vehicle available on demand will tend to make them buy smaller cars. 4. Even when it's hard to find parking in an area, the car can drive itself to areas where parking is less scarce. Overall my guess is that all of these are going to effectively increase the amount of parking available by 4-5x. Parking simply won't be a problem anymore, unless of course this induces demand, we build higher, and without parking garages...
