Discription of Events: I was driving south on highway 59 on the left lane and suddenly, from the right lane, this chevy Cruze started to merge as if I weren't even there. I stomped on my brakes to avoid collision and blared my horn, but she kept on driving like nothing happened. We came to a red light, and I pulled out my phone to take a picture. I saw in my rear view the people in the car behind me were pointing and discussing what they saw. The light turned green. Then we all came up to another light, and she quickly changed lanes again without a blinker, and not giving another car much space to brake just so she could be one of the first cars in line at the light. I had arrived at my destination after this light turned green, thankfully. This person really shook me up.
