An idea would be to get the relative pos of the hit vehicle (that would be done by a script which detects the nearest vehicle, and you put as exception the ID of the car the player is driving and then you get the pos of the bumpers, doors, etc. and see if the player's car is very close to them) and then do whatever you want to do with the script.

*This is just an idea, I don't think this will be 100% accuarate*
