Since I waited too long to take action, I think that I really need to wait until 'next time' to report her. However, I have decided to wave (5 fingers, open palm) every time I see her in the future. Part of it is to let her know I know who she is, but also people seem to be programmed to have a harder time screwing with someone who acts friendly. I may get a helmet cam.
After my ride home last night, I decided I needed to chill out a bit. I always use my mirrors, but I've been scanning more than usual looking for her. Well, last night, I see lights from a truck that looked like hers coming up accompanied by a little right drift, and then a honk. The honk was a bit tentative, and just as I turned up my head to burn as many details as I could into my mind so I could call the cops immediately with a great description, I realized it was a friend.
My friends honk at me because I tell them to (and they know to do this ONLY to me). Keeping my reflexes trained helps me stay calm and decisive when the real thing happens. For the time being, I'll quit hunting for her and just wave when I see her. We'll see if it makes a difference.
