I dont, but just speaking from experience on how assembly line operates, when there is pressure, or pushes to meet some sort of insane expectation, then the whole mfg team/cycle gets the intense pressure, its just nature that the more pressure the more things can go wrong =P (from what I have seen in my experience on other assembly cycle). Given also Tesla QA/QC is not top notch to begin with =P from what we have seen in the issues with many one deliveries... I certainly hope they can be the exception as I am awaiting mine delivery (could be in next week).
