Kev,
we know you're contributing your valuable time and considerable skills to the event, teaching track virgins where and when to brake, and where and when to turn in, all at nice, sedate, bring your car home in one piece speeds.
How about you keep doing that, and leave the charity and publicity side of the event, which for your information, is one of the primary, if not the primary, object of the event to the important people?
Then you would have no need to get involved in any no good half baked ideas.
