Discription of Events: At the 9th St exit on Hwy 101 in San Francisco, male driver of the white 2015 and up Mazda 3 didnt like it when I got into the other lane first as he was trying to get into that lane as well. At the stop light at the exit, he squeezes his car in front of me and blocks me in. When the light turned green, he did not move for about 10 seconds, then when he starts moving, brake checks me. Luckily, I was able to avoid hitting him. After that, he blocks me when I switch lanes twice. At the next stop light, he puts his car in reverse to try and hit me. After the light turned green, he switches to the left side lane and tries to follow me. Only after I turned to another street, he left. This was all captured on dash camera.
