I can say it will impact, but at the same time, they are;
1) revamping the Fremont production lines during this downtime, so maybe will be as productive as their tent version, and thus increase production when they come back online,
2) I'd think they'd not full on WWIII retool their entire facilities for the ventilators. Ventilators are much, much smaller production lines than cars, and maybe have they'd dedicate one production line equivalency to that;
And 3) Shanghai has much higher margins than Freemont, and they're rapidly ramping their production lines. If, say, the margin on the Fremont line is 15%, and the GF3 is 30%, they'd only have to produce 50k cars in Q2 to cover 100k worth from Fremont. That's only about 4.5k cars a week. I think the last ramp was about 3k cars already, so they're doing pretty great on that front.
