How to park? Back on to the tiny circle in the tiny spot. (sensors on the outside of your car  will be screeching to help guide you in) the circle will rotate your car 180 degrees to an elevator. The elevator will open, an attendant drive your car on to a one spot conveyer belt. There are several cars above and below. The attendant gives you a number- say A23. Your car is now in the equivalent of a car vending machine. When you are ready to retrieve the car, enter a passcode and A23 – the car miraculously appears in the opening of the elevator.
