There's a common pattern in population dynamics that I've observed, which probably has a formal name: A given system with (to simplify) two types of behavior: good and bad will tolerate and self correct up to certain percentage of bad actors (call this the jerk threshold, JT) after which all participants switch to the bad behavior. Examples are line formation for a service, cutting people off in traffic, stealing fro…
They've actually had to try to make people more of a jerk in the midwest, and instruct them on why the "zipper merge" is NOT bad: https://www.dot.state.mn.us/zippermerge/ Otherwise if there's a sign that says "Left Lane Closed 10 Miles Ahead" everyone will get in the right lane for ten miles .
And have 10 miles to get up to speed. As opposed to the zipper merge where everyone waits til the last minute, and everyone has to come to a complete stop.
Supposing of course your observations are true. From what I can tell with the "lane closed in 10 miles", is some asshole invariably sees it as a chance to get ahead of everyone else, zooms through the left lane, almost causes an accident, and then other idiots who think he's being successful in zooming ahead imitate his behavior. You get your "zipper merge" anyway, where everyone has to come to a dead stop at the chokepoint anyway. We're not all one gigantic robotic hivemind, preparing early makes for a smoother experience for all and fewer hostile feelings.
For those who use the shoulder on the interstate who do not have genuine medical emergencies (why didn't you call the ambulance?) I propose that they bring in mobile car crushers. I'm even generous enough to let them exit the vehicle first.
