A big "Amen!" to Steve's input. We pride ourselves on the quality of BMW CCA track schools, the antithesis of the "open track days" peddled by some other organizations. In fact, the Golden Gate Chapter, for one, insists on a prerequisite: a car-control clinic (which is a great experience on its own). I also recommend autocross as a good way to find the limits of adhesion in a safe environment. But be careful when you do finally sign up for a BMW CCA high-performance driving school: The experience can be highly addictive!
