This may have everything to do with the contract Fox has with NASCAR. It should be of some consolation that at least you got to see the race. I remember a number of years ago, the local network switched coverage of an NFL game to their home town game in the middle of a play! When they switched, the opening kickoff was still several minutes away. Of course the game they switched away from involved my favorite team and I missed the end of what was a pretty exciting game.
