http://ping.fm/1N48w Can you imagine a automobile with built-in, automatic, folding parking wheels fair under the chassis? The driver will just press the button to activate it, then skate the automobile crosswise onto the tight parking hour without the usual back-and-forth maneuvering. These extra wheels must be able to turn in all direction. The driver can steer it to the left or fair or turn encircling. Just pull off the automobile alongside the tight empty hour, steer the wheels, and park the automobile diagonally.
