I know many good drivers what oil/coolant or clutch is and heck I even don't know my brake levels being a DIY car enthusiast. They just call for service if something shows up on the dashboard or hear something.

That does not mean they are ignorant drivers as long as they know how to drive safely and make regular services according to manufacturer's guide.

Great post! Unfortunately it's on quora

Thanks for pointing to the original article.

Totally agree! Puzzles are just one way of studying human (or animal) behaviour in a controlled environment. It's absurd to be used as the main tool to evaluate a person's competence.
