Discription of Events: I was driving N on I-45 & Nasa Overpass, I put my turn signal and slowly lane by lane I make it to the far left lane. Driver speeding up behind me gets so close to me and flashes his lights that it's all I see in the back window. I tap my brakes because I didn't want him getting any closer, my 16 month old daughter is in her carseat in the backseat. He speeds past me and I put my brakes on so he doesn't hit me and he gets in front of me and STOPS, in the fast lane, with no one in front of him and trying to get me into an accident. We part ways, and I get off of the freeway to go get my son from school, Driver has gotten so far ahead of me, he's the car in front of me when we get to the light. I don't know what his problem was, but I didn't want him running me over in his truck with my daughter in the backseat.
