I quit following NASCAR years ago when the cars quit being STOCK cars. I can see special chassis for safety, no problem there. The cars aren't cars but car shaped things. Even when the car company didn't make a 2 door in a model, there would be a 2 door looking body raced for aerodynamics. The only racing I'll watch is Rally Car racing. At least there you have to be able to drive. Driving in a circle, where's the talent in that?
