I think you should add the option of losing wheels or not in some crashes i think it would be more realistic for exemple this picture: or even this ( but it will like 1% of chance for like each 2-3 minutes or less i don't know up to you guys i'm just here to give you some ideals ) for exemple: P.S. im french / sorry for my english
If I remember correctly the developers have already confirmed that you will be able to loose vehicle parts in the event of a crash that would warrant such activity. This will tie into the 'part system' that they are developing, meaning any part of the vehicle that would detach off of the real car in an accident would do so.
It was pretty funny. That would make a cool race mode: Some parts randomly fall off of your car every few seconds. It would be mostly about luck, since a door falling off wouldn't be as significant as your engine suddenly rolling across the pavement.
