ELI5:What are Tesla cars, and why are states trying to ban them?
gpt
Tesla is a company that makes really nice electric cars. They've been getting more popular in the last few years.

But states aren't trying to ban them. States don't really care what kind of car you buy, but they do care about companies trying to sell cars to consumers (you and me) at unfair prices or in other bad ways. So in many states, there's a law that says when you buy a new car, it has to be from a *dealership*, such as Big Mike's Car Emporium, and not from a car *company*, such as Ford.

This system is old and entrenched in the automobile market, but it worked pretty well. But then Tesla came along, and tried to start selling cars. There are no Tesla dealerships, so what they were doing was technically not allowed in some states. Some people want to remove the dealership laws so that normal people can buy Tesla cars.
