Rain stinks.
So do red flags.
Caution flags, also not cool.
They pray before races.
Most passing I saw was into and out of turns.
NASCAR is popular with all cultures. Period.
The race on tv is usually one of four (at least) that week.
Fans usually support multiple drivers, with 42 drivers it would be a waste to only have one shot.
People want crashes. But get bored of them quick - imagine a fight in hockey taking 15 minutes to fix.
Update:
It was actually an hour and a half - then we left.
Ugh.
