In 1953, Brooks Walker modified a new Packard Cavalier sedan from his California business, Walker Research, and made it into one of the most famous postwar Packards. Using a series of hydraulic pumps and lines, gears, and the Packard’s left rear tire and continental spare tire, he came up with his own unique system for easing the parking procedure for car owners. Apparently nobody bit on the idea, leaving Walker’s prototype, his personal 1953 Packard Cavalier, the only known example featuring the patented system.
As late as the 1970s, Walker was still developing a parallel-parking system for cars, and his last known effort was on a Saab sedan. At that time, he still owned several 1950s cars sporting variations of his self-parking device, including an early-1950s Ford station wagon, a 1957 Oldsmobile station wagon, and a 1951 Cadillac Series Sixty Special. All of these cars were modified from beneath to allow a tire to be hidden under the car until it was lowered in the process of parking the car. Each of these devices necessitated cutting out part of the bottom of each car, and, in the case of the station wagons, mild modifications were required. For instance, the third seat was made to face rearward (which Walker boasted to be the first person to implement) and the rear fenders were extended so that the gas tank could be hidden in the driver’s side fender.
What set the Packard Cavalier apart from Walker’s other self-parking cars was the fact the Packard used the tire of the continental kit to move the car from side to side. This spark of genius brought Walker closer to his goal of making the self-parking system a bolt-on kit that could be applied to any car without changes to its basic structure.
