I was driving on Worcester Rd, Framingham, Massachusetts, and a driver drove out of a plaza in front of me, cutting me off abruptly and I almost hit the side of his car. He stopped the car sideways after I honked at him, almost blocking two lanes, and there were many cars driving past us. Then he briefly pulled to the side to let me pass him, but he cut me off again and stopped the car for a second, then drove off fast swerving the car. I was very frightened and I also had my little brother in the car with me. If I hadn't hit the brakes fast enough, a bad car crash would have occurred.
