Heck- you would be hard pressed to get one of those drivers into a sprinter to run that show. I ran into one of the current IRL drivers, an Indy 500 winner, in an empty airport about 5 years ago. Since the place was dead and neither one of us was pressed for time we chatted. When I told him that I was a sprint car racer, he told me that I was crazy, and there was no way in hell that he would strap into one of those things.
I don't know about you, but I think it's pretty sad when a guy can make it to the big time without being brave enough to race what hundreds of us strap into every week across the country. I doubt you would find a single sprint car driver who wouldn't mash the gas in an Indy car given the chance. (Heck they only have 650 hp, that puts them on par with 360's- and they have wings!)
