I do think Tesla has lost sight of their original plan, though. They should have kept going through one more generation of significant cost reduction/increased volume after Model 3/Y. They are intentionally leaving this part of the market to competitors as they focus on self driving, and I think it's a mistake that will cost them in the near term.
Exact same car 2 decades ago would have cost a hell of a lot more. At which point the lack of bells and whistles would have been a huge problem.
Slate is an anagram of Tesla. Coincidence?
Obviously a very big "if" making it at that price point will be extremely challenging.
