But then you can call AAA and get fixed in under a hour. I would guess the number of truck drivers that know enough about their engine or transmission to fix a trivial issue is <10%. For Uber drivers I would be flabbergasted if it was over 1%. I actually think this is a pretty good analogy. A truck driver does not need to know how to fix their truck to do their job. A web developer does not need to know how to bitshift. For mechanics or low level programmers it is a different story.
