I have put a lot of hours in to this came and on multiplayer 9 times out of 10 I get a blatant ram in a race, mostly on the first lap. Even when I'm keeping well out the way I get side swiped or rear ended.
One solution I can think of is to have an option to ghost the cars on lap 1. I think this would sort the clean racers from the dirty rammers.
Another way is to penalise a clear ram by measuring the force of the shunt.
Please add more suggestions.
