Wisconsin Shuffle

A road rage adjacent driving behavior particularly common in Wisconsin, wherein a driver in the passing lane roughly matches the speed of the driver in the slow lane, so that nobody can go around them. They will each in turn slightly speed up or slow down, creating a shuffling effect, but never leaving enough room for anyone to pass. Often, they will be driving slightly below the speed limit. Causes are myriad but the emotional core is that both drivers feel they are driving the morally correct speed and nobody should want to go faster or have a problem with being behind them. Both are unwilling to go slower and accept the subordinate position of being passed. On occasion this dialectical conflict will explode into full road rage and both drivers will suddenly accelerate, well beyond the speed limit until one of them reaches another car and is forced to slam on the brakes. At this point the humiliated party may follow the victor, trying to drive them off the road for some ways, or slink off to nurse their wounded ego and await a new partner.
