Be polite during qualifying and act like a gentleman. It’s pretty self-explanatory: don’t be an bad driver, give way to other drivers, don’t push them to the side of the road, avoid any actions that could ruin someone else’s race!
Don’t try to win the race on the first lap. Nobody can win a race on the first lap/first corner, you can only lose. Watch the other drivers in the early stages: their last-minute maneuvers and attempts to grab every opportunity in the dense traffic only create chaos and accidents that ruin the race for many drivers. When entering or exiting a corner with another driver, stick to your own trajectory and avoid any last-minute maneuvers. A single lane change before braking is acceptable, but continuous lane changes, left-to-right maneuvering, or lane changes in the braking zone are not acceptable. In tight racing conditions, when cars are close together (not just nose-to-nose, but with the front doors parallel to the rear tires of the opposing car), drivers should ideally give each other half a car width. This gives all drivers room to make corrective maneuvers without forcing their neighbor to drive close together. High/elite racers in motorsport can and do get close, we understand that, but let's remember that we are just amateurs (since we don't get paid to race), so let's give each other enough room to enjoy a tight race without killing each other. Just because you can do something doesn't mean you should. Assess the race, who is next to you and what you stand to gain/lose by doing so. Divebombing is really stupid and often leads to crashes/anger/drama. There is a fine line between using a mistake and Divebombing. If it doesn't feel right, it probably didn't. Focus on overtaking on the exit unless you are next to someone entering the braking zone. Let other drivers know when you are leaving the pit lane and also when you are entering if necessary. We do this as a courtesy to avoid unnecessary crashes as some drivers may not know you are leaving.
