It's one of the main problems with user interface for the really tech-inept. It's a fundamentally hard problem, because you don't know what they're expecting, and you can't predict it 100% of the time.
That said though, most programmery-types are problem-solvers at heart, and would be looking for information when their car broke down. Many people don't even look for the word "help" when stuck on a computer, they just make a fuss and wait / storm off because they fully think it's incomprehensible to them (usually because they haven't tried learning anything about it).
As complex as computers are, take a look at OLPC and similar projects, where a supremely back-water pocket of a society is introduced to computers for the first time. The kids look, poke, and are up and running within minutes because they're learning how to use it. Adults who try achieve the same in roughly the same amount of time. Many non-tech people though won't even approach it as something new, they expect it to be a "magic box" that does what they want, not what they tell it to do (like employees?). Nothing in the world works that way, why expect this to be any different?
