The disappearing car door is labelled a “revolutionary concept in car technology” by its creators Jatech. The disappearing car door is a spin on the convention car door employed in nearly all automobiles today. Instead of the outward swinging hinged doors we are all familiar with, they have developed a door that retracts down into the body of the vehicle.
