As I was riding today, a car pulled out in front of me, I swerved and went around. I looked over as I went around saw the kid (17 or 18) and flipped him off. Rolled up to a stop sign and this kid was on my ass, I quickly went through 3 gears and put some distance between us. I now come to a red light as I'm waiting for it to change this same punk rolls up and again is on my ass (within 4" of my tire). Light changes and this kid is tailgating me (had minivan in front of me). Came to another stop sign and I pulled to the curb to let the sob around me. As he passes I yell "you're F***ing dangerous". I pull back out and next thing I know the lil bastard break checks me, he came to a complete stop, I got around him and as I passed I punched his side view mirror and shattered it. I then put alot of distance between us and that was the last I saw of him.
