I recall an anecdote about a mathematician being asked to clarify precisely what he meant by “a close approximation to three”. After thinking for a moment, he replied “any real number other than three”.

Julia Child did some 400° cooking, for a science-oriented TV series called “The Ring of Truth”: https://www.youtube.com/watch?v=WQ3mjb9BSaU&t=850s
Later in the episode, she got to cook a diamond to amorphous carbon. “I’ll remember that recipe – one carat diamond, two and a half hours, three thousand degrees”: https://www.youtube.com/watch?v=WQ3mjb9BSaU&t=1458s

When I realize the car or truck ahead of me is emitting something I don’t want to breathe (either because I see it coming out the tailpipe, or because I start to smell it), I want to switch to recirculation RIGHT NOW, not after I navigate through a maze of menus that require me to take my attention away from driving.

Also, I want temperature regulation based on how hot or cold I feel, not what some thermometer says (and often have different opinions about where the air should be blowing depending on how I feel).
