Maybe that's true in the NW, but it's not true in the Midwest. I know a lot of NSX owners who track their cars - some casually (once or twice a year, or not even), others frequently (four to eight times a year or more). I run into folks driving NSXs frequently at track events held by BMW CCA and by CGI Motorsports. In fact, I would guess that more NSX owners track their cars than Porsche owners or Ferrari owners.
Heck, it's not even true in California. At NSXPO '99 at Laguna Seca, the largest NSXPO to date, there were 119 NSX owners signed up for the track event - 12 as instructors, 107 as students (not counting several dozen non-owner instructors). This was the first track event for 39 of the owners; for the other 70, it was not their first track event, and 30 of those had driven in 10 or more events.
Of course, the numbers since then have probably gone up, not down.
Compared with NSXPO '99, the percentage of owners with track experience at other NSXPOs has been higher, but the number of attendees has been lower, with drivers in the track event numbering 50-70 each year. The majority (not all, but the majority) who attend each NSXPO come from the immediate area and surrounding states, and thus do not represent double-counting of attendees from other years.
