Discription of Events: Kid is messing around in his car with his dog or something else. Keeps slowing down. I get over pass him. He decides the car in the center lane is going to slow so he then changes lane (no blinker) in between me and the car in front of me. Very little room. He decides to flip me off. I go around him and when I come to a light I guess he thought he would try and scare me by opening his door. Whatever. He turns into Castle Hills (very upscale community). I guess he feels privileged. Either way, another example of someone not obeying traffic laws and doing other things besides driving and somehow, its my fault.
