Rage Report: Stay Right Except to Pass

Is it just me, or does this piss everyone off? I thought everyone learned the same rules of the road. Stay right except to pass seems like an easy one. It's called the passing lane, after all. Or even the fast lane which seems self explanatory. So why is it so many people are willing to sit in the left lane and coast at the minimum speed? Do they do it on purpose? Or is it that people are so busy; sucking down a Starbucks, talking on their phones, yelling at their kids all the while a Disney movie plays on two screens in the background that they have very little idea what's going on outside of their vehicle? In that case wouldn't you think they would enjoy the lower pressure right hand lanes? I just don't understand why we have to work against each other. Are we not part of a society? From now on people, I beg of you, pay attention to the traffic around you and move over if someone else needs to pass. Life's hard enough already, let's try to work together to improve traffic.
