Racing at Bristol requires much skill but little speed. Real racing happens only on super speedways. Daytona, Talladega, and Pocono are the true racetracks. Take Talladega, where the average speed in the 2000 DieHard 500 was 161.157 mph. The super speedways provide racing at its best.
Speed is the key.
Even with those limitations, the cars are pushed to their limits at a place like Talladega. A driver must simultaneously drive with skill and caution because even the slightest damage to the car can ruin a driver's chance of maintaining the necessary speed to win. Sure, it takes skill to keep control of a vehicle being bumped from all sides. It takes skill to strike the right balance. That only happens on super speedways.
