if you know a lane is ending/closed and you get in it to get ahead of others who are currently in front of you in slow/stopped traffic .. i'm sorry, but that doesn't help anything. do you honestly think the people in the other lane don't see the empty lane? do you think you are somehow smarter than all those other people? all you are doing is keeping traffic moving at the exact same speed if not slower as the sudden braking to let people in can cause more disruption than volume. the only benefit is that you, individually, are further ahead... so again... why do you *deserve* to be ahead due to your own self importance? (not meant at anyone, more an open note kind of thing)
if it is regular driving volume and the lane ends, whatever.. get over at the end and hopefully people understand a zipper pattern. no issue there whatsoever. at a light? why wait through one more light, so i get it for sure.
too often the people who get into the closing/ending lane think they get priority over the other lane though... they should get no thought and should be on their own.. it is not the persons duty to let you in because you wanted to get further ahead... it is your duty to find a way in. people forget that they might not be the first car that has squeezed in in stopped traffic and if people keep doing it, then the open lane won't move, traffic gets held up more and people get more angry. and after lights, you are the one who got to skip ahead a light, so get over when you can, don't force it thinking they are supposed to get out of your way or *have* to do a zipper pattern for you.
