While the concept is great, I agree that unless SCCA sanctioned non-competition HPDEs (think NASA) that such a concept isn't workable. Such an HPDE program would be more effort than is currently expended on Club Racing since the turnout would be greater due to the lack of a licensing requirement.

I can forsee a voluminous and politically charged "Instruction Qualifications and Teaching Methodology" program that would probably exclude half of the current licensed racers for various and sundry reasons. This would coincide with HPDE stewarding program, the HPDE registration program and the HPDE F&C program.

While it would be nice to "keep it within SCCA", that's not necessarily realistic either. Some folks like to herd by marque (think PCA or BMWCCA) and enjoy being the big fish in a little pond. When they enter SCCA, they become a small fish in a big pond that's full of different cars where they can't "shine" as readily.

As was mentioned, SCCA is very much a natural progression for drivers who start out in HPDEs or marque clubs. As the drivers improve, they build dedicated track cars and look for a greater challenge than just driving around a track alone. Some of the marque clubs offer racing but with marque-specific rules that (IMHO) provide a class for every car and a car for every class so that everyone's a winner - in other words, it ain't racing but more like really fast parade laps with some passing.
