On a local highway (OH 562) I signaled to move over to the right lane where there was plenty of room. Instead of letting me in, the driver tried to close the gap and keep me from changing lanes. Then when I got off the highway, she cut in front of me on the ramp and stopped in the road. I went around her and went on my way. She then chased me down, cutting in front of me in traffic, and continued yelling at me as we sat at a light. As we continued, she was in front of me, going very slowly. I tried to change lanes a couple of times to go around her, and she kept changing lanes to keep me from getting around her. I finally dropped back so that she wouldn’t have time to react, and took a different route.
