Right. But if you go all the way up to the front, passing people who have 
already zip-merged, then you're ignoring the rule that keeps the traffic 
flowing.

The problem is that this person gets to the front, the person beside him has 
already let someone in, and now there isn't enough room to let this second 
person in without slowing down and making a hole.  Not just a hole big 
enough to merge into, but a hole big enough to merge into from being stopped 
instead of being at the same speed as traffic is already going.

In order to efficiently merge safely, you have to have both lanes finished 
merging before you get to the end of either lane. Zooping up to the front 
just because the people before you have already merged means you're no 
longer zip-merging. Instead, you have a zipper with an extra tooth on one 
side, and you know how well *that* works.
