Could there be badges and/or accolades added for cleanly winning races? Say, win 100 online races without touching anything (AI cars, walls, lamp posts, cars driven by online players etc) and get a badge (something like a red cross with a tick in it - whatever fits best)? A second one for 200, maybe a third for 300. Know it’s a small thing, but it might help encourage cleaner racing and discourage rammers.
