Discription of Events: Driver in a white SUV speeding behind me (while my baby was in the backseat), started to tailgate, when I refused to speed up driver used center turn lane to pass illegally. Once in front of me driver slammed on brakes, then continued to speed down the street. Made a right turn, I turned in the same direction, driver was tailgating another car in the left lane while I drove in the right. After I passed in the right lane driver changed lanes without blinker to tailgate my car with its brights on, again while my sleeping baby was in the backseat, then changed lanes and made a left turn, still not using turn signal.
