it's not fair when racing and others are crashing into you on purpose every race i can name 3 players who do it for there gain it's called cheating if they hit you hard enough your least likely to finish the race or go pit and repair car which might as well quit same players every night
Save the replays and send it to game admin explaining what happened and when. Are you playing with free or paid content? Are you racing on official ranked servers? Generally behaviour is a bit better on servers with paid content or private room servers run by league communities, but the tradeoff is the players are also better.
