You have to give Tesla Motors Inc (NASDAQ: TSLA ) credit for attempting to change the retail rules of a century-old auto industry. In hopes of one day transforming the outdated dealership experience, Tesla CEO Elon Musk argues: "Existing franchise dealers have a fundamental conflict of interest between selling gasoline cars, which constitute the vast majority of their business, and selling the new technology of electric cars." Musk also makes the valid point that because Tesla Motors Inc (NASDAQ: TSLA ) doesn't have any existing franchise dealers, it isn't violating automotive franchise laws. Of course, North Carolina isn't the first state to test the brakes on Tesla's retail plan. The EV maker has testified and won the right to sell its cars directly to consumers in other states including New York, Florida, New Jersey, California, Colorado, Oregon, Washington, and Massachusetts. Where goes the Model S?
