SpaceX has that and they have Gwynne. So do pretty much all other car manufactures, specifically with electric cars.
Having great service while scaling is insanely difficult. Just having some other influentual manager is not gone magically solve that incredibly difficult problem.
Overall the company has been anything but messy, rather they have been executing pretty well, better then most people expected.
I don’t know what people expected but I expect them to miss deadlines with the harder stuff where they’re trailblazers (like autopilot).
But building a reliable car is largely a solved problem. Even Elon has admitted they over engineered the manufacturing before they had to just use more people.
They continue to innovate and have been strategically investing in becoming a battery provider and building and expanding factories in all the important markets.
And building EV at good margin is defiantly not a solved problem.
Let me be clear. I own a Model 3, and I love it. I also own Tesla stock. And I cheer when their sales go up.
My criticism is from wanting them to be better. They've got all the really difficult stuff right (the car is amazing, comfortable, and we all love it). It's the easy stuff that's "boring grown up stuff of running a business" where they need a lot of help.
