There are studies that show merging late actually reduces congestion: https://www.nytimes.com/2016/10/13/us/why-last-second-lane-mergers-are-good-for-traffic.h

  An Exit lane is probably a different situation from the one described though, and so different behavior is better.

    Yes, I figured I probably wasn't clear enough. I agree with the points in the article but I'm referring to a different situation. For example, the one that kills me every morning is where the 101 S turns into the 134, there are 2 dedicated lanes for the 134 on-ramp (so no zipper merge) but people wait until the last possible minute to force their way into the dedicated lanes and clog both those and the surrounding ones. Similar situation where the 170 S hits the 134.
