I was on I-24 today in Illinois going into Kentucky when I got behind a harley davidson. He saw me and sped up. We were in the left lane passing traffic, so at first I thought he was just being nice and getting out of my way. But after he was clear to get into the right lane I saw him downshift and violently twist the throttle open. Of course his bike was just abnoxiously noisy. I downshifted and nailed it too. Slowly I caught him and then passed him. I honestly thought that he would leave me.....of course I was in my 95 trans am with the a.c. on.
