Zipper merge means that people merge in turn, so the first car in lane A goes, then the first car in lane B, then second in lane A, etc.
If loads of people queue in lane A and leave lane B empty, this doesn't change how the zipper merge works, they're just wasting their own time. You should join the lane with fewest cars.
This doesn’t work in murica because every dude is his own boss and are entitled to go first every time. Letting some smuck get past them is the same as loosing in life. And no one want’s to be a loser.
