A number of months ago, there was a story of a traffic jam in Chicago cause by a slow-moving Prius in the fast lane with GreenPeace sticker all over it.

This does
not help hybrids or environmentalism. I personally find ways to hypermile while making it easy for other to pass by....
I must be the member that vents the most about aggressive driving. I've found that the time of day and the route I take can help a little bit.
I've wondered if a psychologist has ever suggested to a patient to walk around at work, home, etc. they way aggressive drivers do. How many people would cut others off in the isles, step on toes, etc. with this body language "Get the **** outta my way!!!" If that is unacceptable behavior, it should be even more taboo to drive that way.
