I'm totally confused.
I was driving with the wife to Longmont, CO. We were on Rt. 119 and came to a stoplight. I was in the left lane and a newer Buick Regal (one of the supercharged ones with the 240hp V6) was in the right lane. When the light turned green, I took off at my normal pace, which is usually a little quicker than traffic around me but nothing really dramatic. I started to pull ahead (believe me here, racing or performance driving was the last thing on my mind. Our house was being shown to some prospective buyers and we were discussing that at the time). The Regal accelerated at a pretty good clip to get in front of us and turned his right turn signal on for 2 blinks and shut it off. I didn't think anything of it. In fact, I hardly noticed at all.
We got to the next light and it was red so we stopped in the same lanes, him in the right and me in the left. Once again, we both took off from the light and he pulled ahead of me and flashed his right turn signal again twice. This time, my wife and I looked at each other and were saying "what's that all about?". This time, the road was 2 lanes each way and 55mph limit for a couple miles until Main St. I was just cruising at about 60-62. He slowed down to around 55 so I was starting to catch up to him and actually got to his rear tire when he sped up again and flashed that right turn signal twice again.
This time, I just said "screw it" and dropped it into 3rd and stomped on it until I flew by him at around 90-100. He tried to keep up but that big boat had no chance at all. As soon as I got in front of him, he turned his high beams on and left them on until we got to the next light.
What the f*#$ was that all about? What did the right turn signal flashing mean? Was he just trying really, really hard to be a ****head? If so, he succeeded famously.
