When playing MP on high latency / load servers, the physics collisions being determined by the server differs from the client profoundly. For example, stopping a tank going 40 km/h 5 m away toward a stationary truck will ram the truck without touching it and damage it to the degree that it explodes.

I can understand this kind of experience with the system of lag compensation that Arma 3 MP has if the truck had been following the tank and with the tank suddenly stopping. But this one is beyond an acceptable issue.
