I'm a new FEH owner (2 weeks in). I haven't noticed any other FEHs or MMHs around here, but I see plenty of Priuses and probably some others I haven't recognized. However, they're always going the other direction or somewhere other than beside me. Today, however, I made my first contact with a fellow hybrid driver. On my way to work this morning, I was sitting at the stop light and noticed a Prius behind me. Since I knew he wouldn't be jetting away from the stop light, I pulled away slowly to increase my EV-only time. After we were away, he pulled into the other lane, and as I was turning left, he passed and gave me the "wave" acknowledging me as a member of the club. I felt so proud.
That's it. Nothing earthshattering. Oh, I did get 27.2 mpg on my first tank of gas, but I'm still breaking her in and re-learning how to drive. I suspect it will get better.
