If it helps, think about this: the car steering is actually the one that is inverted. When a car is moving in reverse, the angle of the front wheels is inverted relative to forward motion. For tanks (and mechs apparently), they do not have such an inversion, presumably because steering a tank is accomplished by making a speed differential between the tracks, and that remains constant in either direction. Perhaps mechs have a similar system, such as using their gyro to lean while turning?
Also that illustration of MadogPL's bears a striking resemblance to the graph of a tangent function:
Any mathletes care to correlate?
