The same thing happened to me, except I kept passing the car over and over when it was stuck in traffic, so it got annoying really fast. I asked the driver to roll up her window while we were both at a light but she ignored me. I contemplated squirting her dog in the chops with my water bottle, but instead I just took the lane in front of her at a leisurely pace until I got to my street. I think she was pissed.
