The car manufacturers actually lobbied for laws that prevent them from cutting out dealerships, to remove barriers to entrepreneurs investing in building brand-exclusive dealerships. The dealerships wouldn't have been built without these laws protecting them, that's why the manufacturers lobbied for them. The legal system in place was a precondition for the development existing American car dealership network, and I doubt that the dealerships are going to go down without a breach of contract fight.
