God yes.

I am generally a nice-ish person. I'll try to slow down a little to give them more room. And then they just slow down too because they don't know how to drive without matching speed with a car next to them. And, fortunately, they aren't looking at me so I can't even wave them in. So it is just a waiting game of "Are they going to speed up and cut me off so that I have to slam on the brakes, or are they going to slam on the brakes at the last second and stop their lane until my lane stops to let them in?"

Nobody is saying to force your way in to the merge lane five miles ahead of the closure. If traffic is moving along, move along. But if you see an opening and know the lanes are going to merge? Merge then and there.
