How many NASCAR fans watched the superbowl?

To answer your first question I did not watch the superbowl. Sorta forgot it was even on. As far as your next question goes, my husband and I were wondering the same thing. What do Mark and Jr get out of it other than bragging rights if they win? Is that worth possibly wrecking your 500 car? Seems risky since all of those other guys are fighting for their starting positions or fighting to get in the race.
