Since I do a lot of projects for car companies and no I cannot tell you which ones, I have a little insight how a production ramp works. I cannot say if Tesla does the same, but since several do, I guess it is at least similar. Some people have been wondering why 30 then 100 then 1500. Usually it works like this: Production Candidates are not made by hand, they go through the assembly line, however the line is stopped at each station and manually stepped through robot steps to check if everything is OK. First Production will much be the same, with a Quality Engineer walking beside the car and some robots might still be stepped. That is the month where most car manufacturers make 10-50 cars only of that model. Then the production line is started, but at a very very slow speed (usually around 1-2 inch/s or 2-5 cm/s). Still Quality Engineers will walk with each car, so not all "slots" are filled with actual cars, so there will be space between each car. Usually 100-300 cars are made this way. Less if the line has to be stopped to tweak something, more if the line goes on and everything is fine. So my guess is 100 is lowballing it. Finally production speed 1 is done. That may be anything from 10cm/s (4 inch/s) and may gradually increase with every month. We had lines that took 5-6 months or even a year to reach full speed with up to 300-500 cars per day. I hope that was useful info. You may quote this as it is common knowledge in the car industry and I have no idea why stupid analysts do not know such things.
