Discription of Events: There were two mustangs driving together the first one cut me off before we got to a red stoplight and the other one tried to, but didnt have enough space so they got stuck in the turning lane. Then as soon as the light turned green they gunned it and cut me off and almost hit me just to have to make all of us slam on the brakes because there was a truck going really slow in front of us. The mustangs also almost hit a pedestrian and kept driving recklessly and speeding until they were out of sight.
