As I pulled up to the stop light I noticed this older toyota corolla or such (i.e. not a fast car) in the left lane, I am in the center. The light turns green and I take off in a spirited manner up to about 5-7 over the limit which is 40mph. All of the sudden the Toyota comes flying by and slows down so that I pass him and he stomps it and passes me again. He wants me to race him but I'm not interested because there was no need. We get to another light that was red but this time he was in front of me in the middle lane. The light turns green and he takes off, if you can call it that and immediately moves to the left lane so I goose it in second and run up to about 55 or so and then slow back down to 45. There is no traffic in front of us and it is a 6 lane road divided by a short median (3" curbs with rock filler). He starts doing his pass me and slow down routine again. Well when he does this for the 4th time I let him pass me so he is about 1 car ahead, this is where I decide to take the bait so I stomp it in second at about 40-45mph. When he's about 3 cars behind my Valentine 1 goes bonkers so I stand on the brakes and bring it down to 40-45 from just about redline in second. He flies by me and then I see the source of my Valentines warning coming the other direction. The cop instantly slows down and climbs his car over the median, blasts past me and follows the toyota into a grocery store parking lot.
