Discription of Events: The female Asian (60s) driver and I were driving down Stoneridge RD toward the new Pacific Pearl shopping center. There are 2 lanes. She was driving on left lane (fast lane) while I drove on the right lane (slow lane). As we drove, I saw this driver put on her signal indicating she wanted to switch lanes which was fine however she failed to speed up and made me brake so hard because she didnt give me enough space as she almost side swiping me and the car behind me almost slamming into me from behind. The female driver should have sped up to pass me, then change lanes safely or wait until I passed her to change lanes. This driver almost hit me all because she wanted to shop at Ranch 99. Dumb B*tch!!
