You're not wrong about that - there were news reports that Tesla was having serious issues with their car assembly line too (not least that parts of it weren't even there yet, and the parts that were there weren't working properly and would likely be hell to fix due to Tesla skipping a bunch of the normal steps in having such equipment designed and manufactured).
