It is known. It caused by the player(s) computer(s) and the host server being out of sync and then suddenly having two vehicles in the same spot instantaneously.
Make sure both vehicles are “owned” by a single player (this is usually not necessary if pulling out of a hole or river feature ie. a very short distance). Drive with a March order at most. Avoid trees and buildings which cause major course corrections. Tell people not to hop in and out of either vehicle including yourself. Don’t let anyone ride in either vehicle to operate the weapons.
But this is not guaranteed.
