No one was born in the correct lane at the beginning of time. They inserted themselves there at some point. In traffic, the only way they could have done so is to move in front of another driver.
Zipper merging [0] exercises a different kindergarten skill, taking turns. Still, "lines" are a small minority of lane-changing situations, all of which involve taking the open space in an adjacent lane.
Yeah and zipper merges don't increase traffic flow, they combine backup congestion so that the impact of the selfish driver is minimized. It is implemented so those who will not take their turn as intended don't have as much negative impact on other drivers.
"Lines", to use your emphasis, are by far the major time component so for me this is a meaningless distinction. Normal traffic merges should of course be accepted gracefully.
