The video above is an interview with the winners of the LA Auto Show Design Challenge, Robocar 2057. The VW designers imagined cars that stand upright, which allows for higher traffic density. On the slipstream highways, things really get interesting as the car rotates to a flatter more aerodynamic position. The cars have spiked wheels that let them drive on the side of vertical highways. The cars also have a wing on the rear that keeps the back aloft. The vertical highway idea reminds me of the magnetic highways in the movie Minority Report. The standing car idea reminds me of I-Real. Below the jump, find a video interview with the director of the Design Challenge.
