Japanese people know how to rice a car (and scooter, van, etc.). That's some crazy stuff. I will never, ever understand Japan.
A couple of weeks back, I saw a Chevrolet Silverado in a parking lot and I could have sworn I saw its rear wheels turning. I thought I was crazy, but it turns out that you can actually get 4-wheel steering as on option. Apparently it's adaptable; at low speeds, the rear wheels turn in the opposite direction of the front ones to reduce the turning circle. At higher speeds, the rear wheels turn less, and at high speeds, the wheels turn in the same direction as the front wheels so the truck can sort of slide sideways as it moves forward. It's really cool. I can only imagine what that kind of system would do in a car like the Mini Cooper.
