Daily Doings at the Line of Death Bar & Grill

People who merge early when a lane is closing. Once traffic has ground to a halt, best behavior is for cars to merge alternately at the point where the obstruction occurs. This is called a "zipper merge". Merging earlier simply slows down the traffic in the lane that isn't going away -- and it annoys the drivers in that lane (who see cars sliding ahead of them in the closing lane) so that they tend to not allow the folks to merge at the obstruction point!
