Indeed. I would be a little nervous if I were a traditional brick-and-mortar car dealer franchisee right about now. Because if Tesla gets the laws changed, what's to stop the big manufacturers from just selling direct as well.
Existing auto manufacturers have signed contracts with their existing dealers. All states have laws that protect those contracts. Tesla is not attacking those contracts and those laws.
Tesla's attacking laws that say that all new autos have to be sold by dealers. That's quite different, and only a few states have such laws.
