I don't see NASCAR as being too supportive of motorsports in general. I don't see campaigns to get people out to the local dirt oval to see local people running bomber class or better yet, to encourage people to get behind the wheel and live it for themselves.
I see a lower percentage than other sports where people are passionate about the actual sport, versus passionate fans of their particular driver. This is a shame, as it could be the catalyst of a new generation of people truly passionate about cars.
