    > how fast to slow down (which requires deciding how much to press the peddle)

    Homophone trap; it’s “pedal”

    >How do experts do it? What makes them special? Expertise is not about knowing lots of explicit facts, but instead defined by what we call tacit knowledge; that is knowledge that is hard to articulate because it is so implicit to how we move about in the world.

    I enjoyed this post a lot. Especially since I believe it’s not AI written. The reading experience per se is much more enjoyable.

    in the left-hand turn section, author mentions you need to decide "which lane to turn into" and to the person who almost ran me off the road this morning: there is only one correct answer! don't end your left-hand turn in the right-most lane!

    with that out of the way, i like the driving example. the brain is really doing a lot of processing for something that feels so simple and mundane. another good example was one i read in a book by patrick rothfuss:

    the teacher stands some feet away from the students and says (roughly, from memory) "in 15 minutes i will throw a rock from here, with about this much force, at this angle, and in that direction. calculate where it will land". the students toil over it, doing all sorts of calculations and what not, failing to come up with an exact answer. the teacher comes back and yells to a young boy passing in the hall, and says "catch" while throwing the rock; the kid catches it easily. the teacher says something like "10 of the brightest students couldn't do in 15 minutes that which one serving boy did in a second". the lesson is to introduce the concept of the "sleeping mind" (i think? it's been 10 years) and how much processing the mind does without our knowledge.
