This was in early 2018. The automation in the Fremont mfg lines kept breaking down halting the lines. They couldn't keep the robots running...
Musk was nearly broke, as he had put so much of his PayPal fortune into Tesla.
In an act of deperation, Fremont erected 2 gigantic tents in the parking lot, built mdg lines inside and started assembling the cars far more by hand.
The rest is history. We bought ours in Dec 2018 fresh outta the tent.
This was actually documented in a 60 Minutes episode, with Elon Musk and Leslie Stahl.
Musk explained his demand for extreme automation in the assembly lines, a mistake that nearly bankrupted Tesla. And him.
He took 100% of the blame for his mistake.
Of course things are different now. Musk often talks about his lessons learned.
Interestingly, some advisors have suggested Tesla buy Ford to aquire their world wide manufacturing and distribution capacity.
I believe the Ford family owns too much of the company to make this happen.
