Damage system to stop griefing

I’ve been playing Forza Motorsport since FM2. I have always enjoyed the game and been eager for the latest releases. I know the game has bugs and I can play the game and still enjoy it. The reason for the post is something has to be done about the rating system. I and so sick and tired of being rammed off the road my other players its making me want to give up the game completely in frustration. I feel some kind of damage system like the career mode has would stop people smashing cars off the road . Who runs off the track and then runs straight back on without a care in the world in racing. Please fix this issue im sure im not the only one frustrated
