Coming back to the design, Tesla needs a connector system which will work on a variety of cars which will use the Model S platform.
Maybe the Charge "Pod" at the front of the vehicle could open up to reveal one uber Tesla connector and two or three recepticles which each hold an adapter. The adapters are solid - no cables - and have a tesla plug at one end and a different socket at the other, J1772, Mennekes, whatever. The customer picks their choice of adapters along with the other options (seats, audio package etc). The obvious ones for a particular territory should really come as standard at no extra cost. The adapters are always stored in the front of the vehicle next to where they will be needed - not rattling around taking up space in the trunk or accidentaly left on a garage shelf at home.
The advantage of using the Tesla connector is that if the charge pod door is open then the Tesla uber connector and the bottom of the recepticles can electro-mechanically lock all of the adapters in place when the owner locks the car doors. Adapters can't be stolen.
Obviously some clown can still disconnect the commercial plug from the front of the adapter, but a few arcing incidents (plus this action could be made to set off the car's alarm) and word will get round that this is not a smart move.
trouble is, this just seems more costly/complex than just three different sockets in a row.
