I'm a autocross racer and drive a black 95 R mazda miata. It's not difficult to deal with the male racers, although being 28 and tiny probably helps. Whats most annoying is when I'm not strong enough to do something on my car alone and have to call one of them (ego gets a little brused) but I belong to a few miata clubs and there are a ton of other women out there of all ages!
