How about adding Emergency Disconnect button to Charging Screen as Safety & Security Feature. If one felt threatened when charging at night & someone approached the car, you could disconnect and drive away without having to get out the the car.
@liftsrock - Even if the charge port unlocked, you'd still likely end up yanking the charge cord off given the plug insertion is at 90 degrees to the direction of travel and fits as tight as it does. I'd guess you'd likely totally destroy the charging pedestal. Would require not only unlocking the port but having an ejection pin to actually push the plug out of the port.
No problem. When the car self-drives cross country by the end of 2017, it will have the ability to automatically plug/unplug. Just put the car in gear and it will disconnect.
