Bear in mind that "rocket science" is proverbial for a reason. Are you familiar with the THAAD (https://en.wikipedia.org/wiki/Terminal_High_Altitude_Area_De...)? What convinced me that it wasn't just corporate welfare was the part where one of the tests failed because the target rocket exploded in flight, so the THAAD rocket couldn't even be launched.

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...
