> The signaler needs to have anticipated it and not signaled until this problem doesn't exist
How do you handle an upcoming left turn (assuming right hand driving) during heavy traffic?
It's not the responsibility of the car changing lanes to optimize the fuel economy of the cars behind, but it is the responsibility of the cars behind to not needlessly impede other drivers from getting where they need to go.

Does "momentum towards closing the gap" just mean that you're keeping a higher speed than the car in front of you? I don't see any reason you'd do this unless you have another free lane to the left and are planning to pass. If you don't then you're just reducing your margins to the next car for no reward, as you'd have to slow down anyway once the gap is "closed".
