A short social experiment video in which people mimic the New York subway practice of workers pointing at signs and signals. It makes the point cheerfully.

It is linked in threads on pointing-and-calling and error prevention as a light illustration of the practice.

It's a little late in the game to get this seen, but they do this in the NYC subways too. It made for a great video! ▶ this video

Here's a video of people having a bit of fun with it. ▶ this video (New York City imported the practice from Japan)

A NYC-via-Japan subway practice is another nice example: link which led to this delightful friendly prank: ▶ this video More examples of the narrow and broader meaning: link But these aren't great examples because they don't capture the important aspect of an automated system detecting and reacting to an operator violating the process protocol.
