If parallel parking is your nemesis, you may be a little disappointed the five-wheel self-parking car never made it past prototype stage. The vehicle was developed by designer Brooks Walker in the early 1950s on behalf of Cadillac.



A series of hydraulic pumps and gears would push out the fifth wheel from the rear, so the driver could rotate the back of the car and glide into the space with ease. Cadillac shelved the project but Walker carried on designing parallel parking systems into the late 1970s.
