Tesla has unveiled a prototype charger for its vehicles that automatically (and creepily) finds the car’s charging port and fills it with power, without the driver having to do anything. Elon Musk, the tech superstar who is the co-founder and CEO of the company, teased at the creation of the prototype on Twitter in December last year, writing: “We are actually working on a charger that automatically moves out from the wall and connects like a solid metal snake.”
