I agree WRC is great and really cool to watch, those drivers have huge balls. F1 is boring. NASCAR is great because the races are actually close and ususally decided in the last couple of laps, unlike F1. If it wasn't for pitstops there would be few to no lead changes in F1. In the 05 F1 season only 5 people won a race and 14 of the 19 races were won by either Raikkonen or Alonso. In the first 19 races of the 05 NASCAR season there were 10 different winners and by the end of the season 15 different drivers had won a race. I don't know about you but i'd rather watch a race where almost anyone can win. Also you have to admit it takes some skill to drive a 3400lb car with 800hp on a 12" wide slick.
As for the other shows on Speed, most of them suck.
