This old lady kept beeping at my mother’s car even though there were cars in front of us due to traffic. She was impatient and wanted to pass us. We pulled over to let her go ahead, but to her surprise, there were still other cars in front of her. Frustrated, she got angry at us for no reason and started taunting and harassing us by giving us the finger. When my mom responded in kind, she became even more aggressive, trying to instigate a fight. She continued making faces at us and recording us. At a stop sign, she hesitated and refused to move for several minutes after realizing I was making a phone call. We called the police, but only God knows what they can do. She seems like a bully who enjoys causing trouble and provoking collisions.
