I've repeated this a few times, but I see people lining up in the "open" lane as far away as 2-3 miles and I always find it to be incredible. The lane is not not CLOSED until you get to the merge.
Yet people will line up and wait for an hour or so and then they sure get mad when I zip up to the front, zipper in two or three cars from the dead end and then zip away. I really don't get it, I understand being polite, I don't understand being stupid. Nobody told them to line up so far back.
Even worse are the truckers who decide to play "road god" and think they can block you from going around them.
But I agree... They need to put "proper" zipper merge signs in to make people understand how it should be done.
Not all, but at least some states ate publishing the "right thing" to do... They just need better signage.

Missouri, even acknowledges there are times when a early merge is better; but it is always during light traffic conditions...

Germany has a pretty good sign...
And in my opinion, these signs are part of the problem... they give the impression you should merge into one lane and not zip.
