Hey, I see you come from the same philosophy of driving as me -- the speed at which I am driving is the absolutely correct one. All seriousness aside, though, the problem is much more heavily weighted toward those who drive too slow in passing lanes than those who drive too fast. Still, there are few pleasures more sublime than finally cutting off some clueless cluck doing 35 in the left lane of an interstate.
I think there's more pleasure in keeping Johnny Nascar from passing me on the right while I'm in the left lane waiting for the slower traffic to get out of the way, but these people driving slow in the left lane should not be on an interstate.
