I remember an ad of some car showing how the rear wheels turned in the same direction as the front, aiding in changing lanes. I wondered that it would make turning in a full parking lot quite tricky. I wonder how Honda's Prelude switched from one mode to the other, say if the 15-20 mph were exceded with the wheels turned?
Steerable front and back wheels make the car more complex, but it would allow a smaller angle of turn, making it easier to cover the wheels with skirts.
