If a space program that has been operating for 60+ years can trip up seemingly inane details, I gather Space X may be at risk of over-looking pertinent details, from time to time.

In general, SpaceX seems to be much more competent and much better-run than Tesla. My guess from thousands of miles away is that Musk is just temperamentally better suited to space than to cars. Space exploration is in its infancy, still a bleeding-edge field where every product is more or less a one-off, while car manufacturing is mostly about logistics, quality control, and the effective management of routine in general. I get the impression that SpaceX is the most efficient of all companies and agencies involved in space, even though Tesla is a strikingly inept car manufacturer; I just hope Tesla doesn't drag SpaceX down with it into bankruptcy...
