When Charles Pyott considered the possibility of on-the-fly adjustable camber, he looked at motorcycles, the human foot and cars like the Mercedes F400 Carving and the BMW Clever. What he came up with isn't something you'll find on any of them: the Dynamically Augmenting Wheel System, or DAWS.
Instead of making a wheel that adjusts its angle, Pyott created a wheel split into eight sections that can slide laterally on a special hub and bearing. That means the wheels can have an effective camber change without altering their angle relative to the car, and you keep the vehicle's entire footprint in contact with the ground. Not mentioned, it could also be used to alter the car's track. You probably shouldn't expect to see this in action any time soon, but by the time John Connor gets here...
