Merging early isn’t polite. It makes the jam longer.

Описание: Merging the second you see "lane closed ahead" isn't polite—it’s actually making the traffic jam way longer. 🚗🛑

When everyone merges early, half a mile of road sits completely empty, stretching the line backward and blocking exits for everyone else. Transportation engineers tested the alternative: filling both lanes all the way to the end and taking turns like a zipper.

In Minnesota, zipper merging cut traffic backups by up to 40%. You won't get through the bottleneck any faster, but the line stays significantly shorter and much fairer for everyone on the road.

So be honest: are you an early merger... or do you zipper to the end? Drop your answer in the comments! 👇
