Discription of Events: The woman who was driving this vehicle was really immature. She decided to cut in the slow lane in front of me and slam on her brakes to try and make me cause an accident with her vehicle on Thomasville Road at 7:48 this morning. Prior to this she was traveling 55 mph in a 45 mph zone. She then was blasting music like, "Bette Davis Eyes" and Eric Clapton's "Layla". When we were stopped in 8:00 AM traffic, she was texting while driving, which is illegal in the state of Florida. She then turned on to Maclay Road, where she used the lane to turn right only to bypass the car in front of her. She was then traveling 60 mph in a 35 mph zone on Maclay road.
