Somewhat related, I recently learned about plain stereopsis and why it matters for motorcycle safety. https://youtube.com/watch?v=doSDfIo61r0&si=wNo0PKsEaUWdxd

  Awesome video. Anyone who rides a motorcycle (or really any e-bike, scooter etc) ought to see this TLDR: the combination of one-eye depth perception and a small vehicle means when cars entering a roadway check for traffic, they will see you as a rider but they won’t be able to judge your speed- and therefore they will assume you are going the normal speed/speed limit. So as a rider, don’t travel faster than that around intersections

  There’s an annoying tendency among YouTubers to string what is usually a 10-second explanation into 5+ minute long videos with unnecessary gimmicks, putting the meat at the very end. TL;DW on stereopsis: 0) Both eyes are required for depth perception; 1) When drivers quickly check their left and right, the extremes are covered only by a single eye; 2) With neither depth perception nor secondary clues (like distance between the headlights in case of a car), the speed of an object coming directly at you is impossible to assess.

    That trend is called 'monetization' if you look at historical videos you can even tell where youtube keeps changing the minimum length for monetization.
