The Substance (2024)

I think you’re there with the last bit of your comment. The goal isn’t to only move once, the goal is to minimise stops and starts. If everyone does this is a self sorting system. If someone has the rule “try to only move forward once every x minutes (unless you are at the front or the queue overflows)” then the queue gets into a rhythm that works.

In a queue like this there is extra effort in picking up your bags and stopping so the worst case scenario is everyone moving exactly as space is available.

First time I’ve seen these guys, that was great.
