In my opinion, Tesla is a fantastic luxury car brand and will continue to be so (assuming they can continue to get funding for their plans).

That said, I don't think they will be able to compete in the midrange and economy segments. The competition is too fierce, and their key value proposition (their brand) isn't as helpful once you're dealing with budget-conscious consumers.

In my opinion, Tesla shouldn't have gone after the mid-market with the Model 3. They should have continued to compete against BMW, Mercedes, Porsche, etc. where they have a durable competitive advantage.
