Crazy, aggressive, inconsiderate, road-raging a-holes.
Okay, I admit that I have my bouts of road rage and often get annoyed while driving the streets of L.A. There are so many drivers here and we encounter so much traffic, that sometimes you just can't help it. But to be unneccessarily angry and aggressive? Come on people! Swerving in and out of lanes, cutting people off, and giving fellow drivers the bird? Not going to get you there any faster! All you're doing is adding more negativity to the energy of the world.
So, to the guy that flipped me off on the freeway the other day: I was trying to move over so you could pass me. But you were too impatient to realize that, you jerk!
