Not surprisingly I think you missed the point. And how you came to $500 a month, math must be really hard for you. Point is, if you add up how much all current dirt racing providers cost per year and divide it by 12, you are still way less than what cable TV costs, and they don't show any dirt racing! I think some people think FS1, NBC Sports, etc is somehow free. It isn't.
If you want to watch WoO, then you need to pay for it. It's value is only up to you to decide, not anyone else. But you also seem to miss the point that WoO shows twice or even three times the amount of races vs Lucas Oil or Flo (counting only premier series, most notably LM's).
The good thing is, you have the choice to subscribe or not. If it were all carried by one broadcaster, we'd all be f'ed!
