Whomever is in charge of manufacturing over there seems to be doing well. It took Tesla over five years to get their manufacturing act together. (Which is what the manufacturing experts who quit in 2016 said it was going to take.) But they finally did, and at long last, cost per unit started to come down.
New product development, though, is not going well. The Cybertruck is still not shipping. Nor is the big truck. A Model 2 has been announced, but is not shipping. And, of course, there's Fake Self Driving, which isn't mentioned much any more.
Come to think about it, Tesla as a high volume car manufacturer now seems to work better when Musk isn't around.
