When joining a server, physics might fail to initialize properly. Meaning that when you drive a vehicle into barrier or else, your vehicle will stop suddenly when destroying the obstacle.
If you respawn and retry the same thing, the barrier will turn into pieces and your vehicle will keep moving. Sometimes it happens even in the middle of a game when it worked well previously. I am not sure if it is linked to the player or the vehicle itself.

Expected result : Vehicles always destroy wooden barrier, fences & so...
