Instructors must understand the function of these systems and properly convey this information to their students so they understand their mistakes before they make a mistake that psm cant correct. There is a very good article in the most recent Pano on these systems.
An example of a time where Psm Slows a competent driver is during slightly un-weighted trail breaking maneuvers. Psm comes on and full power is not there when the throttle is put down making a good driver slower. But this is still a much faster way around the track than spinning off the track. This is a severe maneuver and the ecm only can interpret what sensors tell it. So the psm system acts according to programming not who is behind the wheel.
