That’s the thing innit? The line should be spread across both lanes all the way up to the point where one closes.
The person who gets out into the closing lane to skip ahead probably isn’t thinking about it this much. They’re probably just an entitled asshole. But, in this case, they happen to be doing it right.
Everyone getting into the open lane early effectively closes the other lane early and pushes the congestion further back, disrupting other intersections.
If everyone merges into the through-lane as soon as they can, then there’s no bottleneck. It’s only an issue if there was another intersection recently before the lane closure, but typically these are on highways with few if any intersections.
If you have two lanes of traffic moving at a given speed, and try moving both those lanes through one lane of traffic, mathematically it has to slow down, because you’re trying to fit the same amount of traffic through half as much space.
It’s like when you pour water in a funnel, the bottom is narrower so it drains slower than you can fill it.
Or it’s like doubling the resistance on an electrical circuit. It cuts the current in half.
1 car from the left lane, 1 car from the right lane. merging together in an alternating pattern. like the teeth in a zipper. a ‘zipper merge’ if you will.
you acting like the meme is the problem. the car wasn’t ignoring the signs, they were using all of the available space to move forward down the road before merging into the lane.

One by one at the merge point

That only works when people behave like civilized human beings who take their turn instead of trying to skip to the front of the line.

Oh, well the teeth are the cars and the zipper is the merge point (lane closure)
Both lanes use all available space and take turns joining into a single lane at the merge point, minimizing congestion

That doesn’t explain why my air bags wouldn’t work.
