I'm from Michigan, which probably has the toughest anti-Tesla legislation out there. It looks to me like Tesla is getting ready to mount a Federal challenge based on the Interstate Commerce Clause. Our Secretary of State has been stonewalling Tesla's dealership application, and they are threatening to go to court to force her to (almost certainly) deny the application. Once denied, Tesla would have cause to file the Federal suit. Newspaper articles here have said that Tesla has developed a legal argument based on a precedent from a suit (of all things) over sales of coffins. It looked for a brief moment like the legislature would consider changing the law, but it looks like GM has arranged for the bill to die in committee. Unless something happens on that front, look for a Federal suit against Michigan in the next year or so. If Tesla wins, that should help the NM situation immensely.
