But, I tend to get very annoyed when other drivers do stupid, inconsiderate, or dangerous things. I particularly hate when the left lane is closed, there has been signs indicating this for 2 miles, and cars in the right-most two lanes have slowed and merged to keep traffic flowing smoothly, yet jackasses insist that their time is more important than the other folks who are promptly merging in order to keep traffic from being bottlenecked, and zip by before forcing their way into line when the lane actually is removed.

How far in advance of the merge point must you merge to be considerate? Seems to me traffic should use two lanes as long as they are available to be most efficient for the traffic as a whole, and all should merge alternately at the merge point.

This is correct in heavy traffic. In bumper to bumper traffic, merging at any time other than the last possible will slow everyone down and risk collisions. At the merge point, traffic merges in a basic alternating manner.
