I don't begrudge people for having money and nice toys. I was just discussing this topic with a buddy at the track last weekend. What would we do if we had some of the FU money that some of those guys had? Personally, I probably wouldn't track an ultra fast car because I enjoy pushing a car on the track, and a supercar has to be driven at ludicrous speed to push it...those stakes are too high for my taste and just a hair beyond my ability.
If I had FU money: I would want a nicely balanced, light, 250-300hp track car and a good tow rig. Then I would buy some nice vintage cars to have something shiny to putt around town in.
I would say there is a positive correlation, per capita, to driving ability and money. Not because they have money, but because they are afforded more opportunity to get on track and get experience. The paddock talk at the track this weekend was all about the GTR that went into the wall at CMP, not the Subaru that stuffed it in the same weekend.
