1. Tires coming off rim In a crash, a tire should come off a wheel like in a real car crash. 2. Glass shattering I think it would be cool if there were glass particles when a window is smashed and pop tires if ran over. I'm not sure how it would be implemented though. 3. Paint scratching I know this has been suggested a lot, but it would add more realism. 4. Steering wheel popping off Instead of the steering wheel just staying in a normal position and floating over the roof or the bottom of the car in crashes in very weird ways, it can pop off and add more realism. 5. Suspension falling out The suspension can fall out of its original position in crashes and imagine funny things like this happening:
Tires coming off the rim is possible but would be really buggy. Glass shatter particles are also possible but actual pieces that you can run over would make the game really laggy. Paint scratches are also possible The steering wheel floating also bugs me but don’t know what they will do about that Suspension falling out would be interesting. Would like to see if it’s possible.
