| in our vehicles already produces toe-in during a turn. The geometry of the rear suspension produces toe-in through a turn as the suspension compresses on the outside wheels. This produces a very smooth and predictable reaction to the yaw of the vehicle during a turn. Additionally, the quicker the turn-in you create at the steering wheel, the greater the roll of the body will be, thereby producing an even greater toe-in on the outer wheel which improves the stability of the vehicle. The HICAS system essentially enahnces this same effect by way of creating additional yaw to both of the rear wheels. However, because the system's control algorythms are based both on speed and steering wheel position, and also including a time-based reaction sequence, it creates a chassis response that virtually requires your brain to incorporate real-time computational dynamics of its own to properly coordinate steering wheel input that produces the desired effect. It was a nice try, but leaves a lot to be desired....
