Tesla's prehensile car charger plugs itself in automatically

Keep your flying cars and robot maids, we are already living in Elon Musk's future. Tesla officially unveiled its automatic charging system today and whaaaaa? When Musk first announced its development last December, he compared it to a "solid metal snake" and he was not lying. In the video below you can see the charger bend and flex like one of Doc Oc's appendages as it pokes around the backside of a Model S before inserting a nozzle on its tip into the vehicle's charging port.
