I had no idea.
When I'm driving and see a sign that one lane is ending, I move out of that lane as soon as possible. I want plenty of time to make the merge and then not have to worry about it anymore—except for dealing with those obnoxious drivers who speed down the emptying lane and try to horn in at the last minute. Those people are so rude!
But they're right, and I'm wrong.
Apparently the technique of using all lanes until the very end, called a zipper merge, is considered the safest and best way to deal with the lane reduction problem.
They didn't teach the zipper merge back when I took driver's ed, but I can see that it makes some sense. Unfortunately, it has one big drawback: It requires turn-taking courtesy on the part of all drivers. I can imagine it working in Switzerland, or Japan. But in America? I have my doubts. Zippers are great; broken zippers are nasty.
Next time I'm in a situation of heavy traffic—which is where the zipper technique is considered most important—I may or may not have the courage to try it out. But at least I'll be more patient with the drivers who remain in the closing lane.
Unless they start using the shoulder. Then I'll allow myself to be annoyed.
