Here in the UK, I've noticed that it depends on how 'order' emerges in such situation. Usually cars take turns merging. Fine. But where does that happen? If for whatever reason this started to happen early, i.e. well before the lane closes, (and that seems mostly an emerging behaviour depending on where the first driver decided to merge) then most people will continue merging at that point with few people 'daring' to keep on driving on the lane until it actually closes, and those who do that will be seen as jumping the queue.
