The imminent arrival of the self-driving car will change how people move around city streets, but they could do so much more. The Tridika is a conceptual driverless electric vehicle I created to change how we use cars in our ever-growing cities, where space is expensive and limited. Inspired by Thyssenkrupp's Willy Wonka-esque Multi elevator, the Tridika works like a self-driving car you can literally park next to your apartment and use as an additional room. Instead of wheels, it works like a maglev train: magnets lift and propel the vehicle. It pulls its electricity from the tracks, and takes you wherever you command.
