Aside from many honks and also many "Get off the road" comments, my biggest rager case was when my wife and I were going to turn left onto a larger four lane road from a small residential two lane. The car behind us -like us, waiting for light- just started to lay on the horn, for no apparent reason. He then yelled "Get on the sidewalk where you belong". My wife replied "Bikes have the same laws as cars on the roads (or some extent thereof)". This INFURIATED the man. He laid on the horn some more until a passing pedestrian with some kids in tow yelled at the man "They're right! They have all the rights you do in your car, stop being selfish."

The light eventually turned green, my wife and I made a normal left turn to get into the far right side of the right lane and the dude followed us for what seemed like 1/2 a mile, holding down the horn. I just waved.

I came to find out later, he was a regular a the bar down the street and the time of day when we encountered him was his normal departure time after tying a few on... Authorities were notified, but nothing happened.

I started carrying pepper spray from the point on. It may not defend against a car, but if an angry motorist gets out and comes at me, I'm spraying them. Stopping or cornering me, then getting out of the car and engaging is a clear intent to harm me in legal sense.
