Really?
Elon tweeted that total "produced" cars by the end of Sept could be 1500 (if the ramp goes to plan), they *sold* 260 meaning prepped, delivered, sold. Assuming sales are behind production, you can bet that the sales probably represent 2 weeks (at least???) behind production.
If you assume the following
- Sales of 260 represent a subset of cars produced by that date since it doesn't account for cars not sold, but produced by the end of the month
- Their production rate of 'unsold' cars over the last couple weeks of the month was their highest production rate so far (again.. assuming a continued ramp)
Then you can probably feel pretty good that Tesla has produced (as of the end of Sept) somewhere in the neighborhood of 800 cars?? (again.. just a SWAG). This puts them roughly 2 weeks behind where Elon said they would be in my estimation. Hardly time to panic.
