While it has yet to happen to me, I did notice an SUV in the bike lanes of the city. They never got much further than the next red light, and were rather menacing. I just shook my head. At the last light, I pulled along side the passenger side of the van as they were rolling up their window. I looked in and just nodded, we both knew they were in the wrong, and they knew I'd probably discuss the way their mother had taught them to drive.
