Three second gen Prii right in a row. I merged right behind one in a rotary. I couldn't get the cell phone camera ready quick enough to snap a good pic as we were going round, but you can see the red one speeding off and the one just in front of me turning left. I waved to the lady in front of me through the mirror. Somewhat related, and also today, there was another Prius behind me heading up a steep bridge, and she was ridge riding, slowed at the crest, and gained speed with me on the downhill. It was a thing of beauty.
Too many Priuses here to notice that. I got more excited about finding myself in a parade of 5 different hybrids (G2 & G3 Prius, Insight-II, Camry, and Malibu). It was also the only Malibu Hybrid I've ever spotted in the wild.
