Was coming up a right lane merge, west bound on Denison off the Denison/Harvard exit ramp on Jennings freeway, she was in the right lane. There was a vehicle in front of her, I was beside her. I allowed the vehicle in front to merge into my lane. The lady beside me, Blue Ford Focus rushed up and was bumper to bumper with the vehicle I was trying to let merge. She proceeded to get fractions close to my vehicle forcing me to incoming traffic, I had to left her go as to not get into an accident or get car damage. She pulled into the school just off that overpass.
