Are there any "diehard" racing fans out there?

I only like car races, but I've watched NASCAR Cup and last year, some Nationwide as well as Indy and F1. Watched the Indy 500 as a kid and in 2011, at least one other Indy last year, but never watched F1, I don't think before last year. Never have been able to watch races except on CBS, FOX or ABC. CBS covered NASCAR until after 2000.

I used to know a guy at church who watched some Indy and F1 along with NASCAR, although NASCAR is the one he really kept up with. Some other people I've known were into local racing around here. There are a few people on this site who watch several different types of racing (see above). I don't know anybody who watches horse racing at any other time than the Triple Crown races unless they gamble on it.

I mostly only watch NASCAR, and the Sprint Cup at that. I've watched some F1 at times but just can't get into it.

I watch F1, Nascar, NHRA, and MotoGP, all of them a lot. Can't get into lawnmower racing. Horseracing is just cruel, so no, not a fan.

I like all forms of motorsports, bicycle racing too. Not much into horse racing though.

Not me, I am mainly NASCAR, ARCA, etc., but I watch other forms of racing on occasion.

as ong as there´s an engine involved, i´m all for it. best series? v8 supercars!
