A list of interesting points by timeline:
* Early Model 3s were not produced on the automated assembly line but were assembled by hand in the “beta” or “pilot” shop.
* Start-up and commissioning of the assembly line at Fremont did not happen until later in 2017, possibly as late as December.
* During January and February of 2018, model 3 production was less than 500 cars per week. It is likely that battery production at the Gigafactory was still the primary bottleneck.
* Production averaged 1,500 cars per week at first and was increased to about 2,000 cars per week for the last week of March and the first two weeks of April by adding manpower and moving to a seven-day work week. Fremont, not the Gigafactory, was the production bottleneck during this period.
* The $7500 FIT credit will be phased out starting at the end of Q2 in which Tesla reaches 200,000 US sales. Tesla has planned for this by offering Model 3s to Canadian buyers to keep the number of US buyers below 200,000.
