The construction item "Vehicle Gate" does not mirror the other repair and deconstruct terminals in use. At the current moment if you stand in the middle of the Vehicle Gate and look towards the Shield or Terminal it will allow repair/deconstruct, but when facing the terminal and standing on it it does nothing.
I can tell you responsibly that from the moment the car door enters planetside2 this bug has not been repaired. This BUG has been in existence for 7 years.
