Rather than get mad at the left lane losers, we need to engage in a national educational effort. Pass them on the right, then (without cutting them off) get in front of them in the left lane and gradually reduce your speed to lower than they are comfortable driving. For those who have any intelligence (so about 10% of them), the lightbulb might go off and they realize the error of their ways. For the other 90%, they will continue to remain in the left lane no matter how slow you are going, even 15mph in a 70mph zone. These are the ones who are ruining the gene pool and need to be exterminated (figuratively speaking).
