Whether it’s by the use of tiny car-lifting robots or totally spherical wheels, the idea of a car that can move effortlessly sidewise is an endlessly appealing one. Parallel parking becomes a dream, parking garage management becomes a piece of cake. And out of all the ways to make that dream come true, these “Liddiard Wheels” seem like a pretty compelling one.
Designed by one William Liddiard, the wheels are similar to the kind of “omni wheels” you’ll find on some robots and heavy machinery. The difference with these is that they are on an actual car, they have one continuous surface, and they’re a bolt-on modification. According to Liddiard, they can be slapped on any car.
