While it’s been everywhere, what I haven’t seen explained is that it is a demonstration of how the human brain works.
Give the brain a task like “how many passes does the white team make?” and the brain will focus on that – seeing but not registering the moonwalking bear.
The point of the video (yes, the point is something other than “wow! a moonwalking bear! that’s funny!”) is too change the task of a driver’s mind from “don’t hit other cars” to “drive carefully, don’t hit other cars, and watch for pedestrians and cyclists”.
