9. Parccar
Back in 1951, Brooks Walker came up with a design that should have made parking a whole lot easier. Cadillac adopted the new ‘Parccar’ mechanism and installed it on a few of its popular models. It was basically a special spare wheel that got lowered when parking was required. With all other wheels positioned perpendicularly, these fifth wheels helped the car move sideways and shorten the parking to no more than 9 seconds in any conditions. There was only one problem with this invention – the mechanism took almost the entire space of the Cadillac’s trunk! Think your FB friends will like this car prototype?
