Discription of Events: The driver ran a stop sign making a left onto the street as I was driving on a residential street. I blew the horn and the driver had the nerve to blow her horn back at me and put her middle finger up. I sat there in the middle of the street as she refused to back up. I took her license plates numbers down so that I could report the incident. She proceeded to cut her car off with her child in the back seat, took the child and backpack out of the car, and proceeded to walk up the street. I became angry and rolled my window down to tell her you are the one who ran the stop sign so you should be the one to back out to let me through. She called me an ignorant American and began talking in her native tongue with her middle finger up. I only decided to leave the scene because she had her small child with her. A woman who was walking her dog stopped to shake her head at the woman in support of my anger.
