it will be cool if the textures changed after a crash. As scratches on the metal sheet ( carrosserie )
A thing that it needs is parts cracking like bumpers, doors, etc. Aaaaalso damage when exploding and black texture while firing
English: This would lead to endless texture problems, therefore, this would be an optional thing like the replays till it was stable enough. Français: Cela conduirait à des problèmes de texture sans fin, par conséquent, ce serait une chose facultative comme les replays jusqu'à ce qu'il était suffisamment stable. --- Post updated --- This would be really laggy unless you had some NASA launch computer.
