Man, I'm watching this years NASCAR Daytona 500 race on
Youtube right now, and this is just so much more fun and quality than F1 it's not even funny. Also the commentators are really good and seem very passionate. I subbed to the NASCAR Youtube channel and will watch this regularly. I sadly have been losing interest in F1 over the last years, after being a religious viewer since around 1992. This (and DTM) will be the racing sports I'll be watching from now on.
One thing that will take some getting used to is the noise of the cars... In F1 broadcasts, you usually get the sound of one lone car steadily driving on its racing line like meeeeeeeeeeeeeeeeeeeow, and in the NASCAR broadcast its pewpewpewpewpewpewpewpewpewpewpewpew as you have dozens of cars flying by in a pack at 200 miles per hour. It's awesome! I especially like the cams that are buried in the track and will make you want to dodge away from the screen. The action is so fast that I actually get a bit nauseous from watching it :O
Another cool thing is that there is a woman driving, too. Great great stuff, I'm reall happy to have found a new sport I enjoy watching.
