24 Hours of LeMans classes versus Formula 1 on the same track (different race days) as a comparison. The F1 drivers are truly the top of the heap when it comes to driving skills.
I got a racecar game on my system (torx, which is a very advanced free racecar game for linux and maybe windows too, for anyone who cares), and the only way I can beat the computer driven-nascar's is to drive against them in an F1.
Put 'em on an oval and the Indycars will run circles around both of them...
"As I write, highly civilized human beings are flying overhead trying to kill me. They do not feel any enmity against me as an individual, nor I against them. They are only doing their duty, as the saying goes....." ~George Orwell, London, 1941
