The Tesla laws don't sound innocent at all however - I guess most people would agree that it seems pretty ridiculous right from the start.
Why would thousands of entrepreneurs open GM, Ford, and Chrysler dealerships when the manufacturers could just open a store and undercut them? These laws were a promise to protect that business model.
That doesn't mean that such laws are a great fit for our current economy, but it started out innocent enough.
On a sidenote: One could argue whether these laws made any sense, even back then - just image how ridiculous it would be if every industry enjoyed the same "protections".
