Great idea team. In Melbourne we use Kevin Flynn or kevwrx (forum nic) of Driver Dynamics http://www.driverdynamics.com/
Kev is highly experienced, a lifelong driving instructor it would appear, and takes courses from defensive right through to track, trick and protective skills to order.
I myself won't participate due to the number of defensive courses I have participated in, not to mention instructing light and heavy vehicle licensing courses and defensive courses, but I only add that to support my thoughts on Kev as one of, if not THE finest driving instructors I have ever encountered.
