My goodness. Everyone is acting as if the lane was blocked for a half mile. It was 20 cars. 250ft.
Are you agreeing that blocking the lane for a half mile would reduce efficiency of traffic flow?
Absolutely, up to the point of merging into one lane. The more lanes utilized, the more people would get to the merge faster.
You just won't get thru the single lane congestion any faster ...
but you DID get to it faster.
Precisely. By blocking the lane, whether for a half mile or 250 feet, you are delaying people from getting to the merge faster, which slows traffic and is less efficient. So while you are concerned with preventing individual drivers from “jumping the line” so to speak, you are decreasing overall traffic flow efficiency. Now, by doing so for just 250 feet, the amount of incremental inefficiency you are creating is quite small, but it’s there nonetheless. The logic I was taking issue with was the apparent argument that it didn’t impact the efficiency of traffic flow at all, so I’m glad that got sorted.
So let me ask you this: if you merge early and just as you are approaching the zipper merge point, you see someone in the merging lane who has zipped past 20 cars right up to the merge point in front of you, do you let them in?
