Out of every sport, do you think Nascar is unfair in terms of...?

Nascar is a hard sport, it requires physical and mental skills. A driver can lose 10 pounds in one race. You have to pay attention to your car and make decisions that could make of break you. Dodging cars in a wreck is hard and saving a car that is half sideways is fairly difficult, especially at 180 mph. Also i hate Kyle Busch but he took a wrecked car and won the race so its not only cars but how the driver races them
