Occasionally, while driving a vehicle (V3S), the vehicle will teleport into a different location due to some sort of lag or mismatch between the client and server. You will be driving along, and suddenly find yourself in another position. If you end up inside an object, the vehicle will be damaged or explode, and the player will either take damage or die instantly. This is an issue that desperately needs to be fixed before vehicles become valuable endgame projects.
