I'm not sure there's a huge difference between the fan fascination with the big crash in racing as the fan fascination with the big hit in football. As to the overall difference between the sports, I'd say football's skill set is more on obvious display than those of the drivers (you rarely see a pudgy driver, so yes, they do have sports-like skills). I, too, don't understand the fascination, but I don't mock it, as some do, 'cause, well... I love women's basketball.
