Tell me one thing that NASCAR has that F1 doesn't have.
Until that can be successfully answered, I'll never think Nascar is on the same level.
Close competitive racing where most races are decided by less than 10sec with the majority of them are less than 5 sec. Drivers that seem more like normal people compared to f1 drivers who seem more like movie stars.
The average between 1st and 2nd at the finish in NASCAR last season was 1.65 sec while in f1 it was 9 sec. 9 seconds is huge on the race track. At 150mph 9 sec is 1980 feet.
