"If a part has a problem, only a small quantity needs to be shipped back to the supplier who can inspect, correct, and quickly adjust their own production process."

Isn't one of the advantages of having a minimal, electric vehicle that there are fewer moving parts?

Telsa is in a interesting position as a software/car maker. There production line is like an algorithm they are adjusting on the fly, and it's obviously going to be messy when you don't have multiple decades of manufacturing experience.

Still, Tesla's learning curve is steep, and the M3 is a much more simpler car. Don't be against Elon, it's quite possible he'll be able to figure out how to make 10K/week once the kinks are figured out.
