You could try locking the doors so they can't even attempt. By locking the doors when the vehicle is streamed in.

public OnVehicleStreamIn(vehicleid, forplayerid)
{
    switch( GetVehicleModel(vehicleid) )
    {
        case 599, 596, 597, 598, 497, 520, 528, 425, 427, 532, 490:
        {
            if (!AccInfo[forplayerid][Police])
                SetVehicleParamsForPlayer(vehicleid, forplayerid, 0, 1);
            else
                SetVehicleParamsForPlayer(vehicleid, forplayerid, 0, 0);
        }	
    }
    return 1;
}

Tidied up a bit by using switch.
