If there is a right turn only lane, and a straight lane, and the right turn only lane is backed up with people queuing, you are not making traffic go faster by merging in at the last second. You are slowing down a bunch of people trying to turn, and blocking the people trying to go straight.

You can change straight/right/left here and it all holds. Zipper merges are for merges, when 2 lanes of traffic become one, and everyone merging early is a little bit worse. Above is just selfish.
