What do you do when erratic driver confronts you?

Question

There was this ham-fisted Norm from Cheers looking guy that was driving earraticly and harassing other drivers and bikers. It was rush hour, but traffic not too bad, I suspect alcohol. He started yelling at me at an intersection and I just tried to calm him down. What can one do?

Answer 1

pull out a knife and tell him to f*ck off.  even if you dont mean it, it will shut him up

Answer 2

I would ignore him and hope someone kicks his butt. Nowadays with all the crazies carrying guns on them, I'd be afraid to flip him off or tell him off.  

Answer 3

You should have taken down his license plate number and contacted your local police.

Answer 4

If you think he is going to come after you, call 911 and try to get a good description of the car and if possible the license number.  Usually the best thing is to slow down or turn off and get away from crazies.
