There's always a back story. Years ago before the S, when they were building the Roadster, Tesla reps got all the manufacturers together for a discussion about charging standards. Nissan, MB, BMW, even Toyota and those others that were completely disinterested in EVs or anything to do with them. All of them were disinterested in establishing a standard. Not Nissan, BMW, MB, Ford/GM. It wasn't that they could not agree on a standard. They didn't want anything to do with EVs. This was before the i3, the RAV4 EV, they didn't care. So, Elon said, they had their chance, we will do what we will do.
So, if you are going to get mad about there not being a world wide standard, don't blame Tesla, blame those others. Those of us that have been around here a long time, remember this. Who else remembers?
