female driver. was riding my taillights on 43, i'm already in right lane to take atkinson exit. continues riding my bumper all the way up the ramp. i yield and move to left lane on atkinson to get out of her way. shortly after she comes flying by me going 55-60, cuts me off, and then brakes to a complete stop right in front of me at a roundabout that no one else was at. i wasn't able to brake in that short of a distance and smashed into her backend. tried to be civil with her after the incident and all she would say is that "i should be held accountable" for her assriding, speeding, and reckless driving. my car is ruined, hers has a cracked bumper.. this lady is a whackjob!
