Do these courses make you faster drivers?
Any one can drive a car fast. Just look at all the dickheads the police chase. It's being able to do so with a high degree of control and being able to regain control of the car if you start to lose it. The courses teach you to be alert to what is going on around you whilst maintaining a vehicle safely at high speed, how to spot potential hazards etc and how to react should the vehicle start to breakaway.
You mean anyone can drive a car fast in a straight line.
So basic car control and awareness is what they teach then, and nothing that most enthusiast car drivers dont already do
I know you dont, but some coppers who have had this training, seem to think it makes them into a driving god
You get it a few times at karting open events, after the event having being lapped once or twice they will have been bought down a peg or two back to reality
