I suppose I'm different...I just relax, ease back so I'm not on the bumper of the car ahead, and enjoy the drive. Who knows why someone up ahead is driving slowly, it doesn't automatically imply selfishness. Perhaps they are very old and don't see well, perhaps there is a problem with their car. In any event, I view speed limits as a MAXIMUM allowable rate for traffic, based on average traffic density and visibility. No foul in driving a bit below the limit. It is the fool who attempts to pass in an unsafe manner who causes an accident. Sometimes life provides you with the lesson you need the most, if you frequently find yourself being "impeded" by slower drivers, perhaps you need to learn patience.
