Why would drivers with an open left lane not only drive adjacent to

Aggression towards someone perceived as weaker is a time-honored way to
prop up one's own feelings of power. Chickens, chimpanzees and humans
all do it. It's the basis of bullying in all social interactions, and
best of all bullying is now a socially acceptable activity as
demonstrated by our Furor. Who needs Twitter when you have a ton and a
half of steel at your command and pedestrians and bicyclists to
terrorize?
