Hmmm, that's a good question. I think that it must have something to do with the fact that F1 has 17 races a year, all in different countries. This very fact leads me to believe that it appeals to a much wider demographic than any other motor sport out there. As for the pitbabes, alot of them are models that are payed to be there and look good for the cameras. Some of them are fans, some are not.
