I don't know about other people's road rage, but mine is caused by idiotas living in COLUMBUS, GA that have no idea about the basics of driving!
Hey you stupid Chevy Tahoe soccer mom when making a turn at a turn light you stay in your frickin' lane and do not maneuver into my lane while turning or while I'M on the side of you and almost causing a side collision with my Grand Marquis!! I had to blow my horn at you dolt and get into the lane with oncoming traffic to avoid your ass (luckily no oncoming traffic was COMING then)!!! How could you not see me? You really need to get your eyes checked!!!!!!!
Gosh can't wait to go back to my homwtown of Atlanta where even though they drive crazy too they at least understand the basics of driving!
