Unlike Germany with its highly rigid and regulated traffic system, here in the United States, most drivers lack a fundamental awareness of zipper merging. Zipper merging happens on occasion if the drivers at the merge point coincidentally get on the same page. There is no systematic guidance. Instead, when drivers see a lane closure ahead, they merge early. This is thought of as a courteous thing to do. However, this early merge is slower than the zipper merge since both lanes are not used. It also causes stress on the road. People that merge late are considered inconsiderate; although it is not their fault because there is no guidance on how lane closures should be handled. Merge Like a Zipper educates drivers on what the zipper merge is and to start practicing it in everyday life.
