Assume the new line produces 4x the number of packs with the same amount of labor. The new line machines arrive from Germany and are being assembled. At that point you are literally a short number of days away from drastically cutting production costs. From a financial standpoint, it makes sense to shut the old line down. The new line will more than make up for the lost production of the old line very quickly, at lower cost. Tesla having sent out the massive invite set on 2-22, and following it up with another one a week later pretty much confirms a big jump in production is imminent. The tracking spreadsheet shows a big drop in VIN assignments from 2-22 to 2-27. The VIN assignment is now back on track. If the new line is running, we should see a big jump in the number of VINs assigned, corresponding to the big jump in invites. Big jump in deliveries is the last domino do fall. RT My recent Model 3 invite and subsequent configuration has brought an almost Zen like clarity to my thought processes!
