Detect who is in vehicle and relay hint msg to opposite team

[DurbanPoison]

hi there!

Does anyone know how I would go about detecting if a east player has entered a vehicle and to relay this information to the enemy via hintsilent? Ideally it would just be simple enough to add to a empty vehicle's init.
Im trying to simulate a reported vehicle theft for my mission - with random empty vehicles waiting for da chop shop thx in advance to anyone who can helpsh!
