I follow F1 closely. The back door boardroom crap is a little out of hand though.
IRL - I have the same problems with that as I do with NASCAR, except more so. They are crazy running open wheel cars on ovals side by side like that at those speeds. One tap and they're gone and into the wall. If I'm gonna watch roundy round it's NASCAR.
Champ Car - I like it, but they are going to lose all of their talent to NASCAR if they haven't already because being in Champ Car doesn't pay much in terms of money or fame. It's really sad what Tony George did to CART and American open wheel racing. It used to be held in nearly the same regard as F1 (or at least there you could make the argument without being laughed at) and now both leagues are semi-jokes.
My favorite series though they aren't really popular at all:
The first two are actually run by NASCAR...
1) Koni Challenge (almost no TV coverage this year, though it had some last year under a different name). This is Porsches versus BMWs versus Mustangs, and others.
I like it because the cars actually look like production (i.e. stock) cars and probably started life that way before being modified. NASCAR with the COT is heading straight toward being a glorified version of the old IROC series with everyone driving the same car. On road courses you can just play with the gearing and the weight to make the cars equal. On a superspeedway it is all about the aerodynamics so I know why they are mandating identical cars, but I just don't find that nearly as interesting as a bunch of cars out there with different strengths and weaknesses.
2) Rolex Sports Car - with Daytona Prototypes. Not production cars, but there are different chassis designs.
3) Speed GT World Challenge - productionish cars
4) American LeMans series - sort of a closed wheel version of F1. The winners usually run off and leave everyone.
Since I can't afford to race a car, this is what I do (that is actually me).http://www.pbase.com/sardian/image/64278234http://www.pbase.com/dlathem/image/64420684
No feeling like it.
