The System is used whenever a hazard requires a manoeuvre. A hazard is something which requires a change in speed, direction or both. The benefit of applying a systematic approach to driving is to
reduce the simultaneous demands on the vehicle, the driver mentally and the driver physically. That is, the System seeks to separate out the phases of a manoeuvre into a logical sequence so that the
vehicle and the driver avoid being overwhelmed by having to do too much at the same time. For example, braking and steering at the same time place greater demands on the vehicle's available grip and
in the worst case can lead to a skid.
