For example, you're on a highway and the lane to your right will merge into your lane ahead. Traffic is stopped, the right lane is clear, so car(s) behind you leave your lane, passes you and then merges ahead of you. They've essentially cut-in in front of you causing you to be further behind and stopping/waiting even longer.
Not only is this frustrating but I think with more lane switching back and forth, it causes more traffic than less.

One interesting thing I have found through vigorous scientific testing is that it seems when there is an accident or construction and a lane is temporarily blocked causing a traffic jam... the BLOCKED lane tends to move faster than the open lane next to it.
