That does not explain away others who would relish the idea of setting up an electric only dealership. He is using an pretty damn thin excuse to not allow others to sell the cars. Sorry, but there are many other like minded individuals who would very much sell the cars the way he wants, they may even improve on the methods.
Local dealers for electrics would provide the benefit of tighter integration with supporting businesses, from those who install the requisite plugs at homes, to marketing the need of stations to employers so that their employees can charge up at work. There are many many benefits to having local, private dealers.
