In a hurry to get to work?
We all run a few minutes late, we all hate rush hour commuting (those of us who can not or will not take RTA). The point is that people seem not to drive during rush hour, but it is more a positive display of the chaos theory. The graceful and sometimes not so graceful act of careening your vehicles down a paved road is a recipe for disaster.. The, to often, played game of "get so close that nobody can sneak in" results in accidents like the one show above.
Just relax, and be nice. Just because some over zealous jerk cuts in front of you don't get upset. Realize that if you get into an accident your day will be far worse!
