I agree that that model would be awful, but I think maybe that that is too simple of an analogy. We do already have fuel stations which are exclusive right now, in the form of card access only truck stops which only dispense diesel fuel. There are also similar fuel distribution mechanisms in the marine and aviation industries which dispense different types of fuels (Bunker fuel, 100LL, Jet-A, etc.) which can't be used in automotive applications. The biggest difference here is that electricity, thankfully, is the same in any form, and the key differentiator is the speed at which you can deliver it. I definitely hope that we can agree on better, faster, common, charge delivery formats, but I wouldn't want to put a hamper on innovation, particularly when the electrical automotive industry is so nascent.
