Seems like this may be more of a FIA vs. Speed Channel confrontation than them dropping it for viewership or to make room for other programming...
The FIA is legendarily greedy. Probably saw the rising viewership and asked a ridiculous amount for TV rights.
Of course, the more we pressure Speed Channel, the more they can justify paying the price!
Don't waste another minute waiting on parts, or anything else. Just get out there and start racing! You will suck at first, and you will be slower than many other cars, but the only thing you will regret is not starting earlier...
