Well last night around 11PM I was driving down 680 S on the fast lane going about 70. There was this IS330 on the 2nd lane and it just pulled in front of me while I was approaching. I continued to follow him for about 2 miles and he wouldn’t move. I change lane to pass him up and he went faster. I drop it to 3rd gear and start gaining on him. Can’t believe my 3rd gear goes all the way to 110MPH. I finally passed him and change to the fast lane. He then went faster and starts tail gating me. I moved to the 2nd lane and to let him pass, but he just stayed the same speed next to me. I then floored it and he floored it too. I downshifted to 3rd and start gaining again. We passed the Andrade exit and I was looking at my rear view mirror and I saw a headlight turned on and moved. I then slowed down to 65 and moved to the 3rd lane while the IS330 kept the speed. A few seconds passed by and there was a CHP next to me looking at me. He then speed up and tried to catch the IS330. When the CHP was approaching the IS330, it went faster, he probably thought it was me. The CHP finally turned his lights on and they exited off mission blvd.
