This isn't the first state they did this. Michigan, Maine and a few others come to mind. GM has even gone on record saying they will actively look for places they can convince politicians to block Tesla.
Personally I find this kind of behavior pretty sad. Mostly considering no other large automaker other than GM is doing this kind of thing. And this is why it is hard to take GM seriously in the EV game. Just like when they released the EV1 and then crushed them when they saw they posed a risk to their model.
