Racing etiquette

[200sx]

At times I think some racers are completely devoid of etiquette.

It's fair enough people don't care about breaking their own vehicles but damaging someone else's is plainly not acceptable. To have your car t-boned by a back marker every lap after lapping them three times, chunking your tyres in the process, is not on.

Is there a set of guidelines we should follow to minimise collisions?
