Robotic plug is for HOME use!
In case everyone missed it, Tesla's robotic plug-in technology is intended for HOME use, not for its public Superchargers. The title and photo used for this article are misleading in that regard. Model S owners, like me, do 99% of their charging at home at night. This is usually accomplished with a 240V/40A outlet, and it typically requires only 2 to 3 hours of charging per night. I rarely charge on the road.
Tesla's free public Superchargers require only a 15-20 minute charge for each 150 mile leg of a trip, and they are located near food, shopping and other services. You don't sit in your car while charging unless you've got nothing better to do.
