Texas residents can still get a car from Tesla--they'll just have to order it from out of state, and in the meantime deal with hog-tied Tesla showrooms that will show cars but can't even give potential owners a test drive. Why's that? In short, because dealerships have a lot of cash and a vested interest in the status quo, according to a new report from non-profit group Texans For Public Justice. Acting as the go-between for companies and consumers is how dealerships make their money, and if legislators repeal or loosen laws, the dealerships cede some ground. Tesla is the only car manufacturer using this business model. Plus, compared to other electric cars, and even compared to dinosaur-fossil guzzlers in its class, the Model S is selling well, making it all the more of a threat.
