So I am on my way home from sawmill rd area. This is about 3:30pm today I just got on 270s and need to get over and I was on my bike at this time. I had my signal on and a red Porsche Cayenne would not let me over so. I sped up a little got in front of him safely. Then he came to the left of me rolled his passenger window down and through a plastic bottle at me. It hit my head light bounced off and hit my helmet. I sped back up got next to him and was pointing at him as in pull over. he took off so I chased him and was thinking you nerd you can't out run a bike...lol. So were coming up on the westerville rd ext he cut 4 lanes over almost louse's it and get's off the westerville rd ext. I would have done the same thing but I figured i already got his plate # so I'm good. I hope they find this guy. This is way not cool. If I see your car next time u better pull over or if its in a parking lot I will call you in and wait for the cops to show. This is how people on bikes get killed because you people can't drive and do the most stupid things You are so lucky I didn't get hurt. I could have been killed and ran over by car's that were all over 270. I got there plate #. If you guys and gals could do me a favor and keep eyes out on this guy I would really appreciate it very much.
