My impression is that the line is sufficiently finished to produce cars. This is supported by the statements by Tesla saying they are producing cars on the line, the observations of cars moving down the line and exiting the line.
Is it completely finished? No. Is it producing high volume? Probably no. My guess is that GA2 and GA3 are doing maybe 500-600 cars/day and GA4 is doing maybe 50-100 cars/day.
Just for clarity. The video was posted on Twitter from an aggressive Short trying to show that the line does not produce cars at June 26th. What I tried to clarify with my posts is that the video is very likely (as explained) old and not done at June 26th in an attempt to mislead media, shorts, longs and readers.
I am fully with you that cars are produced in the "tent structure" already. We have videos that do prove this.
