Crab Driving Car And Reverse TRIZ Engineering

The video below shows a functionally very stunning car, capable of performing 4 different driving maneuvers, so necessary in cramped urban conditions. From the point of view of reverse TRIZ engineering, it resolves the physical contradiction: The 5th wheel system of the car (shown in the video episode) should be to provide easy parallel parking, AND the 5th wheel system should not be to further improve car maneuverability.
