I'm not saying people should understand the inner workings. I'm saying they should understand how to use it or at least want to learn. I'm talking copy-pasting files, navigating folders, reading instructions, that sort of stuff. Read my comments before assuming my argument.
In your analogy it would be knowing how to use the steering wheel and the brakes and the basic rules of how to drive, and I sure as shit hope you know how to use them before you're allowed into the streets in your car.
It's like giving a book to a person who doesn't know how to read and refuses to learn how to read. They don't want to read, then they probably shouldn't have a book. They need the book for whatever reason? Then they must be taught how to read.
