There *is* a valid argument that if you don't enforce an existing law (or selectively enforce it), it's a reason for the law to get thrown out. Therefore, I do not blame the NADA for trying to get existing laws enforced, despite the fact that they are ridiculous (imo).
But the laws were intended to protect dealers from manufacturers competing against them with their own cars
I think NADA is digging their own grave here. If they left it alone, these laws would have likely stood as they were, and manufacturers would not have been able to compete against their own dealers. HOWEVER, by fighting against Tesla, these laws will get a good look, and stand a really good chance of being reversed, perhaps even by SCOTUS. This could mean hard times for dealers all over the country.
