You are driving an Expedition and she "nudged" you into the breakdown lane?
If you had a car full of kids, I see you giving ground.
OTOH, if someone tried to do that to me and I was alone, I would be sure to write down the license- I drive a 1 ton Chevy truck with BIG mirrors- and then we would have a tussle about who is going to push around who. My truck weighs about 6700# and has a good COG. I have liked driving it because I figure I have the "Law of Gross Tonnage" on my side.
Sure hope you get a lic # if this ever happens to you again. AND FILE CHARGES---In Calif, it would be assault with a deadly weapon- The car being the deadly weapon.
I had my two small children (3&4) in the car or else I would have been far more agressive (she would have been in the ditch). I did call the police but in Maine (where I am anyway)it takes them awhile. They did come to the house after and I filed a report but because they didn't see it happen they couldn't do anything (typical). My husband now makes me take our two dogs English Mastiffs with me when I go out. They are enough to scare the s**t out of anyone.
In the Chicago area, we can hit *999 on the cell phone and reach the State Troopers emergency line for calling in road ragers and drivers like this IMMEDIATELY. I've done it many a time, and will continue to do it. I will say it helps to make a quick mental note of the color/make of the vehicle if possible. I "memorize" the license plate short term by saying it several times out loud until I get into the *999 system.
