I'd imagine it would take that. I mean you're driving a car at around 200 miles an hour and weaving around a bunch of other cars going at that speed. 1 tiny mistake could be disasterous. You would need to learn how to take precautions in order to avoid these tiny mistakes.
Personally, I' not a racing fan (although I loved the cartoon speed racer) and I don't know anybody who is, and I'm not sure about the origin of the basis of the joke, but I would venture a guess that there a lot higher concentration of nascar fans in the midwest or other typically "redneck" areas.
By the way, the term redneck was originally referring to pickup truck drivers, because the sun could shine through the back window and cause a sunburn on the back of their neck, whereas with a regular car that didn't happen. People eventually involved this into a stereotype.
