Driving Slow in the Left Lane

Nothing parallels "life" as much, or in as many ways, as the act of driving in traffic.  Every single metaphor and analogy you can think of has an identical match in traffic somewhere.  Nowhere does it become more apparent than getting stuck in a rush hour traffic frenzy, in the left lane, behind someone who insists of driving BELOW the posted speed limit.  Nevermind that driving AT the posted speed limit in the left lane should be punishable by severe beating.  Driving BELOW the posted limit in the left lane should be punishable by severe beating, shooting, kicking, more shooting and another beating, and their vehicle should be pushed off into the nearest ditch and burned.
