I was riding along minding my own business i wasn't going slow i was going at lease 40mph. When someone in a SUV started riding my ass, and honking his horn and such so i started pedaling faster, we enter into a under ground tunnel now i have no choice but continue forward as fast as i possibly can. So while in the tunnel, the guy in the SUV rides up besides me, matches my speed and begins to push me with his car towards the gutter/curb. now if i braked i would have fishtailed and the cars behind me would have hit me. So i had no choice but continue till i was out of the tunnel where i had about 50 yards left. So he keeps pushing me to the point that my pedals started scraping the curb, we finally reach the opening of the tunnel where he ramms me into a curb. my back tire slams into the curb immediately going flat and i fishtail out of control intro thorn bushes by the 405 freeway here in Long beach. And the guy in the SUV jumps onto the 405 and goes East.
