Car repair is just pretty far down the list of things it's important for most people to be able to do. I have a general notion of how cars work but there's relatively little I could do on my own. (And, of course, it's increasingly difficult for even indie garages to do a lot of things.)

I do wonder if selective schools have over-rotated in the theoretical direction though that's a debate with a very long history. I'm reading a bio of "Doc" Draper, for whom Draper Labs--which designed the Apollo Guidance Computer--is named. And I was just commenting to a friend literally last night that I bet a lot of the very hands-on engineers who tinkered as much as they did theory like Draper and Doc Edgerton (inventor the strobe) and others would probably never have gotten faculty appointments as prestigious universities today.

Personally, the courses where I did hands-on work are some of the ones I remember best.
