Discription of Events: He came up behind me FAST, flashed his lights once..gave me no time to get over ( even though everyone had just slammed on there breaks and we were all still just starting to gain speed again) so i was barely under the speed limit if not going the speed limit at that time. he jerked around me and screamed F*U and flicked me off with his window down. Then proceeded to swerve in and out of out cars in front of me cutting people off constantly!
