Has anyone on this site ever driven a car for 4 hrs at 200 + miles an hour? It is very physically demanding. And you need extremely fast reflexes and nerves of steel to avoid dabree and other cars on the track.
I am not saying you need to be Bo Jackson. But it definatly take a highly developed skill do drive a race car successfully.
I defiantly think it's more of a physically demanding sport then Golf. If you want to call ether a sport.
