Dealership lobby? Tesla is fighting against them in some states.

Is there really a need for a dealership lobby to protect this practice? I don't think exclusive distributor agreements are that uncommon for all sorts of merchandise.

What competition laws are those?

Doesn't the US have any laws against cartels and monopolies? Wouldn't this fall into that?

I can understand only one official dealership per area, but it seems odd if there are no other dealerships allowed.

It's not a monopoly because there are competing products sold by other dealerships.
