i thought someone was coming out with a car that would move sideways into and out of a parallel parking space
So the 'sidewall' and 'tread face' are one and the same. I wonder what that will do to foul weather traction.
The bit where it says it could be used in robotics made a lot of sense. I can't say I'd fancy having it on a car: directional stability at highway speeds might, I think, be a little compromised. It does look cool, though. And it's very clever.
