Nothing is more frustrating than planning a trip across town and giving yourself an extra 15 minutes in order to not be late to your destination only to have some halfwit that doesn't give a rat's rear about you or your valuable time boxing you in or in some other way working his/her tail off to keep you in your place: BEHIND him/her.
Honestly... I believe that I can understand rode rage in cases like that. And the kicker? According to the law if you are one of those that gets frustrated with one of these boorish, discourteous, unceremonious a**h**es then you are the one that is the criminal.
