The nice part of this system is that its impossible for the connector to short on anything when its not plugged in because of the built in switch inside the housing. If its not connected you can short the prongs with a paper clip and nothing happens. So its completely safe.

Also if you forget to unplug it and drive off it will pull away and not hurt anything.
