"Try an experiment: go the speed limit in the center lane of the highway and see how many furious drivers pound their horns and flash their headlights"
Yeah , I wonder why that could be. Perhaps because some arrogant ass is blocking the lane when he's supposed to move over if the nearside lane is clear. If you want to play traffic cop go sign up and do the 2 years training, otherwise get out the fecking way.
Yet those same furious drivers will inevitably pass on the right into dense, slower moving traffic, ride someones tail until that driver gets nervous and speeds up enough to let them pass that center lane car only to further pass into the the left lane which was open in the first place. The moral of the story is, once you hit the highway, someone is always an idiot to someone else whether you are actually driving like an idiot or following the letter of the law.
