I had never heard of "zipper" merging until I read this post. It would make perfect sense if drivers in the real world drove the way the drivers in the animation shown (in the You Tube video posted above) drove. However, in real life all of the drivers in the open lane would be bumper to bumper, instead of moving at a steady pace with enough space to allow a merge without risking an accident. I like it when a trucker blocks the lane that is soon to be closed off, because that gets everyone in line earlier, and avoids the line jumpers. I don't care what the Nebraska DOT preaches. People just don't drive, in real life, the way the cartoon cars drive in the demonstration video. It's laughable that the "authorities" think they might.
