What are you calling a major? (the old 'Winston Million' events?)
I think a Cup championship should be worth more that a single win even if that race pays alot of money.
Any worthwhile Hall of Fame needs to acknowedge those that made significant contributions to the sport. Besides drivers this includes team owners, crew chiefs, track owners/promoters, and announcers. A list of standards does not serve that end very well.

I'm really not in favor of adopting other sports 'anything', that's how we got stuck with "The Chase"!
