When does, and likely more specifically when it doesn’t, the “Zipper Merge,” applies.

I mean, Minnesota has literally been running this PSA for at least 20 years and it hasn't worked yet, but godspeed to you.

Problem is, they’ve been running a, “Do the Zipper Merge” campaign. Not a, “Do the Zipper Merge in this one specific situation,” campaign.

I noticed some new graffiti in Pittsburgh, they have literally spray painted “just zipper merge!”

This would never work in Minnesota, where a shocking percentage of drivers are utterly convinced that a zipper merge is the opposite of what it actually is, and that they are therefore doing it correctly.

A jingle isn’t enough, they’ll need a series of diagrams.
