Period. Completely. Filling the merge lane when traffic is already slow does nothing but drive density up, which slows traffic further. Sure, YOU might save some time by passing a bunch of cars, but it DOES NOT IMPROVE THROUGHPUT. Zipper merging is about NOT having an area of abrupt speed change. It is not about using up a lane that is going away. Period. Ever. It’s the same as an on-ramp: If you’re speeding up just to slam on your brakes to merge, that’s not zipper merging!
