I don't know what it's like at your local track, but at ours other racers and their families are very helpful. Basically we all want to see everyone have the chance to race and be able to put your best foot forward. Some examples of it happened this week. One of the boys racing in the kid karts didn't have a gas cap. He asked around and another father was able to provide him with one, the same day another kid needed brake pads. My husband had a spare set and was able to help him. We have had days where we were having issues with my daughters' kart and all of the dads and fellow racers were surrounding her kart trying to solve the issue so that she could race.
Everywhere you go there will always be people who chose to be selfish and unethical but I'm so glad to say that we really haven't had much experience with those types of people at the track. I'm sure as things get more competitive and she moves up the karting ranks things will change, but for now I have to say I love the camaraderie and helpful nature of our local racing club. I think that you could call it "good sportsmanship."
