I'm not sure about your statistics.

Yes, many drivers won't ever drive them to a track; however, when you look at general attendance at public road courses, 911s (and less-so M3s) appear to be grossly overrepresented in proportion to their street popularity.

I wish we had better data to work with here.

I think it is safe to say that less than 2% of automobiles are ever driven on a track, so assuming the 98% figure is correct, you would expect to see exactly what you describe.

If 2% of 911s and M3s were regularly driven on a track, I would expect tracks to be full of them.

By that logic, tracks would be filled with the Camry, Corolla, Civic, and Accord, but that's not the case...

I think you took my comment to mean the exact opposite of what it says.
