if canPopulate then 
                            -- create a new vehicle as we didn't have one before 
                            local vehicle = createVehicle( data.model, unpack( v ) ) 
        --[[Like 61]]   setTimer(setElementFrozen, 1500, 999999999, vehicle, true)

vehicle = createVehicle( data.model, unpack( v ) ) 
setTimer( function ( )  
    setElementFrozen ( vehicle, true )
