I just went for this advanced driving skills class today. It was fantastic. I have finally learned to drive my car, as opposed to learning to operate a motor vehicle as I did in my teens/early twenties.
You can check out the school website at:
In the morning, we went over a lecture covering how to properly setup the car, where to look, how to properly use ABS/non-ABS brakes, how to properly execute a turn, etc. We went over a couple of driving exercises, and then proceeded to the racetrack in the afternoon.
It is amazing how much difference a driver's skill makes to the car's overall performance. When my instructor took the steering wheel and put the pedal to the metal around the racetrack, my G35 coupe _smoked_ two Porsche 911s! Definitely one of the more satisfying moments in my life :-)
I would highly recommend this one-day course ($400+) to anyone who operates a car. The skills they teach in this course are very useful even on normal roads, and could potentially save your life one day, were you go get into a life-threatening situation on the road:-)
