True, but tangential. I don't know how far down this rabbit hole I want to go, but years of field experience has taught automakers what effects underbody corrosion has on various bits of the car like brake caliper pins, CV joints, bearings, etc. It has also taught them what has to be stronger than maybe the straight strength-of-materials calculations call for. How brake lines should be routed to minimize the probability of damage. How manufacturing tooling wear affects fit, finish, and initial quality. Where salty snow can accumulate and cause serious corrosion. Seat tracks and springs after years of driving on rough roads. How battery storage areas must be vented. On, and on, and on. They also learn from every recall. They know to go slow and monitor new things, like auto driving software that novice Tesla released too soon. Anyone who has done any kind of engineering or manufacturing management knows that organizational learning and experience is an important contributor to success. As they say, life is like school but first you get the test and then you get the lesson. Tesla's test-taking experience is very limited at this point.
Now, fan-boys and true believers: Tesla's lack of experience is a negative. There are many positives and many other negatives plus a lot of future good and bad luck that will all determine their long term success. And the economic impact of that success or lack of success will show, in hindsight, the stock price range that corresponds to it being a good investment.
