I was coming home from dropping mygirlfriend off when this jack a** in a Lexus was riding the back of my car...I defentially don't drive slow so I figured he was just being a wise guy. We stop at a light and there is mr tough guy pulling next to me on the left side(on the wrong side of the road). Light turns green, we both hit it...neck and neck for a bit but as we hit about 40 before I knew it I was near 70...I kinda walked away from him and he dropped behind me, riding close again. We stop at the next light and i noticed some ice so i wasn't gonna give him another run. He guns it around me hits the ice and starts skidding...he slows down and went to the right a bit( he must have gotten shaken up), I got the idea to pass him again but instead of it escalating I just let him go.
