Tired of whenever you are in a minigame, you spawn a vehicle and leave it parked in one spot, and some person Steals it?
Well, if this is created, this could be the event for you.
One example of usage (With the old variables mod, because i dont know a thing about the new Var mod)
onPlayerMountVehicle > self > IfPlayerID Equals 8385
VariableFalse > Player > Dismount
VariableFalse > Client > CenterPrint > This vehicle is protected
