In my experience in factory production, the pace of trouble-shooting is usually dependent on the pace of production. Identifying issues such as production variability requires data, and verifying fixes requires data. You can only debug if you're making the product. People tend to think "Tesla can only make thousands of cars when they fix the problem". The way I look at it, is that the sooner Tesla makes the 1st few thousands of cars, they sooner these 1000s of cars will enable Tesla to fix any potential issues. So I'm encouraged to see them aiming for 1500 in Sep. Compared with MX, where launch was end of Sep, and delivery of 1000s of cars didn't happen until Jan, this is a much better pace, and promising sign that Tesla can get the production running smoothly soon.
