That's an interesting idea: transporting your whole vehicle somewhere! That way, you could combine the best of both worlds--like flying a plane and having your rental car there.
Reinvent the parking lot: instead of garages, you have bulk transporters.
Go to your garage, order a car ("I feel like a Porsche today") and drive it to work. Return the car at the end of the day, make sure you didn't leave anything in it, beam it back to the rental lot. Like zipcars, except you never have to pick em up or drop em off.
Better yet, you can always have your favorite car with you no matter what part of the country you're in. You take a sub-orbital shuttle to China to visit your girlfriend's dad, your car is waiting for you at the port when you get there.
