epoch, we tested more this afternoon in release version 1.5.6 with A-10A's and cannot confirm this for you with moving columns of vehicles.
However, nearly always, moving trains are drawn in different positions for each client. My wingman says he's shooting a train, but all I see is his weapons hitting the tracks where there is no train drawn for me. Same for him... insisting that I am shooting at nothing and the train that he sees is in another place altogether.
Maybe this is a Gazelle only quirk? Could you try with another aircraft or helo just to see?
