The concept involved a retractable wheel mounted perpendicular to the car’s main wheels, located near the rear axle. When activated, the fifth wheel would lower to the ground and allow the car to move sideways into a parking space. Despite its ingenuity, the idea never gained commercial traction due to cost, complexity, and changing automotive designs. Today,
