Automaker Tesla is opening more showrooms on tribal lands to avoid state laws barring direct sales::Tesla is ramping up efforts to open showrooms on tribal lands where it can sell directly to consumers, circumventing laws in states that bar vehicle manufacturers from also being retailers in favor of the dealership model.
Car dealers are owned by wealthy owners. They have lobbied hard (i.e. $$$) to block other business models via state regulation capture.
Note that most of these laws exist in so called “pro business” red states. Allowing competition and newer, more efficient, business models to replace older business models is a basic tenant of capitalism.
