The P&S 9000 has been specifically designed to make parking fast and simple in garages that are actually too narrow to allow the driver to exit the vehicle after parking. Runners are bolted to the floor inside the garage parking space, with a hinged extension folding down into the drive aisle.
The car is simply driven onto the metal plate outside the garage and pushed into place inside it. The hinged extension is then lifted vertically behind the parked car keeping the drive aisle clear of the runners.
