Nope. Make a mission with you standing on the ground next to an empty T80 named testTank. Make a radio trigger that activates
hint format ["%1",testTank]
Run it on a dedicated server and join as a client. You should see REMOTE at the end of the hint output. Get in the T80 as driver and it won't say REMOTE anymore.
To a client on a dedicated server, all AI, all vehicles (until the client enters them), and all game logics are always REMOTE. All that is local to a player is the vehicle he's driving (on foot, himself). Not sure how tanks work between crew members (but I know they don't work terribly well, seeing things warp around when gunning for a laggy driver!)
I assume that vehicles created with createVehicle start local to the client that created them (doesn't have to be the server).
