text: This is the dumbest editorial I have ever seen, but it helps clarify why these keep right laws are necessary. The left lane is for passing. Period.  Nobody, even if they are going 100 mph, should stay to the left.  Keep right except to pass is one of the most fundamental and universally recognized ways to maximize highway safety.  What is your problem with moving over?  Does it bruise your ego when you get passed?  Are you too lazy to be bothered with lane changes?
