In 1.82 an old OFP feature was re-added (https://dev.arma3.com/post/spotrep-00076 and https://community.bistudio.com/wiki/CfgVehicles_Config_Reference#has... )
Sadly it doesn't work in MP.
Normally one is supposed to be able to drive the vehicle as gunner/commander (aka effectiveCommander), yet this doesnt work in multiplayer (hosted and dedicated server).
