While it's great you have a regional license (SCCA, I am assuming) again - that is NOT what VOI is about. VOI is about the people, the food the partying, the access to DC executives, the other competitive events, etc. It's never been billed as a day for track rats. Heck - usually the Friday before an SCCA weekend, you can run for $200. If you are that experienced, why not stay for viper Days and get a TON of quality track time with other Viper drivers and measure your skill?
The VOI organizers are not going to check credentials and turn people loose on the road course - especially when there are about 700 cars there - you'd be out with 20 other cars on the track and they sure as hell don't have a regional license (some of them are probably lucky to have a regular license....) add on top of that, we're not talking about "run sessions", we're talking about Skip Barber Instructors hopping into cars with everyone from a safety conscious person who just wants to experience the track to a testosterone ****** who's bragged to his friends that he can drive the wheels of his car - and there's a reason VOI isn't about track time.
Take a look at the schedule - the track driving is one line item in an entire weekend of activities.
