I used driving as a way to illustrate the scale of the background knowledge required for the activities. There is a fair amount of background information required to drive safely that has nothing to do with physics. The rules and conventions of the road are not based on physics. Sometimes they seem to be completely devoid of logic as well. Teenagers regularly master these well enough to function. There is little fear that they will have trouble with this. Everybody does it right? (But when that fear is present, it is equally debilitating in the auto world, its just much more rare.)

Neurosurgery on the other hand, is hedged by an impenetrable wall of background knowledge that must be mastered in order to achieve even basic competency. It takes a dedicated expert a lifetime of study and practice. It really should be left exclusively to experts.

My point was that most people think operating to computers is closer to neurosurgery than driving so there's no point in even trying to understand. Just call the expert. Once they realize this is not the case, they often learn the basics fairly quickly.
