Racing Etiquette: (from racerchicks.com)
Drive smooth; the smoother you drive while holding to a good line, the faster you will be. Drive like you have an egg between your foot and the gas pedal. If you are lucky enough to follow a fast car, follow his line. His setup may be better than yours, but you will get a good idea as to WHERE on the track your car should be. That's another reason why it's sometimes best to ask to start at the back. You can see at first hand the way the fast cars maneuver in traffic. Again, this is assuming that the fastest cars start at the back.
Get good THEN get fast; try not to overdrive the car. If you get loose on exit, correct only once; overcorrecting can put you in the wall or another car. If you are assy this means you ARE overdriving the car. Work on your setup. And sometimes less gas means less spin and that means going faster. This is what the pros mean when they say that sometimes you have to slow down to speed up.
NEVER take out the leaders; they have worked hard to be in that position--sometimes it takes them years--and you do NOT want them mad at you. This means hold your line, don't mirror drive (oh, yes, we can tell) and don't race the car behind you. The absolutely worst thing you can do is take out the leader when you are being lapped. Actually, never take ANYONE out. Blocking, checkerboarding, turning your wheels into someone else and mirror driving are NOT racing.
Try to keep your temper. When the adrenalin is flowing, this may be hard. Work on it. Just because someone bumped you, it doesn't mean it was on purpose. Unless it is repetitive, assume it was unintentional or even partly your fault.
Everyone makes mistakes, even the old pros, so learn to forgive yourself. And for Pete's sake--learn how to apologize. "I'm sorry. I screwed up," goes a long way to smoothing ruffled feathers, especially if you show you learned from your mistake and you DON'T DO IT AGAIN. Also, if someone apologizes to you, accept it graciously. Maybe they really DIDN'T mean to hit you!
Most of all, Have Fun!
