Definitely worth a try imho. Would add another layer of complexity, strategy and simulationI still think that the best solution for the problem of people behaving irresponsibly is to raise the damage percentage to at least 50. The current 10% is a joke, you can send it left, right and center and get away with that. SRS, which arguably has about the same or even bigger skill spread (there're quite fast guys, but there's also those who run a Nords lap in 10+ minutes in a GT3 car), uses about 70% I believe, so even a small touch noticeably damages your car which makes most people think twice before doing stupid stuff. That (and the protest system too) has made racing there pretty clean, even in the mid-pack.
Yes, more damage will punish both the offender and the victim, but the thing is that it will do that automatically and there's no escape from that, while right now you can dive-bomb someone and just drive away with minor scratches and you're gonna be OK at least till the end of the race and if nobody reports you for breaking The Golden Rule (and I believe most people hesitate doing so) there're absolutely no consequences for your atrocious driving, especially since naming and shaming in the forum is frowned upon. As for the victim, their race is often already ruined anyway as Ernie's post shows pretty clearly. I watched the replay and I agree with everything he wrote here and can totally feel his frustration. It's no fun racing against someone you can't trust at all.
