How can you fuck up going around in a circle?
That's not a short track. 2.5 mile super speedway. Nearly 200 MPH, drafting, close up racing. One little bump and all hell breaks loose.
Let's face it, people only watch NASCAR for the crashes. Round and round and round on a banked oval for 500 miles, no real braking, no real corners, no real accelerating. If you can watch it and get excited even a little bit you should never, ever, watch cricket, you might have a heart attack from overstimulation!
Daytona:
Le Mans:
Both ~200 mph circuits, Le Mans 8.5 miles with 38 turns, Daytona 2.5 miles with, well no turns really. NASCAR 500 mile race, Le Mans 3000 miles plus. Frankly they're both rather boring, but at least Le Mans actually tests the car's endurance and the driver's skill.
