John Townsend of California-based company Jatech has engineered an amazing retractable car door modification called the Disappearing Car Door in which the door retracts into a clean dry pocket underneath the vehicle which allows standard car ground clearance at all times.
According to the designers, rotary doors have several benefits:
- Cannot be parked in.
- Side mirrors remain in place when door is opened enabling continued observation of traffic from behind.
- Drop door does not swing out endangering other road users or pedestrians.
- No door dings.
- Less parking or garage space required.
- Drop door need not be stressed for multiple slams during its life cycle.
