Well, it's really your issue, not mine since we have Tesla sales and service centers, but I believe you are missing an important disctinction:
The franchise laws which being enforced in WI and Texas were meant to prohibit manufacturers from opening retail outlets competing against their own franchisees. It was a protection in lieu of draconian contract provisions which manufacturers might have put in franchise agreements allowing that competition.
But now, non-Tesla dealers (as, of course, there are no Tesla dealers) are using these laws to prohibit Tesla from competing against non-Tesla dealers. It is completely anti-competitive and disadvantages consumers for the benefit of dealers.
If the laws were originally written with more particularity, they would have prohibited manufacturers from competing against their own dealers, so if a manufacturer (e.g., Tesla) had no third party dealers, it wouldn't be prohibited from opening retail stores.
This really has nothing to do with what ICE manufacturers might or would do. I haven't heard that ICE manufacturers are pushing their dealers to engage in this fight.
