Does it matter? The NA Tesla plug is proprietary, and we seem to get along. So use that plug globally and sell adapters to type 1, type 2, Chademo, whatever. OR, use the type 2 plug in NA. I wouldn't mind if my Tesla came with a type 2 socket, a UMC with a type 2 plug on the end, and appropriate adapters, and Superchargers everywhere were type 2. What do I care what plug is on the car, as long as the stuff that comes with it fits? The Tesla proprietary plug is smaller and more elegant, true, but what they have now with different cords & plugs everywhere is the worst solution.
