He looked like a white-collar kind of guy at least in his 50s probably or 60s. His driving was bit off and abrupt when I caught up behind him on the turn. That and the U-turn makes me think he was trying to lose me. I normally let this stuff go and don't chase down motorists, but I was too angry today to let this one go. He looked intimidated, and I'm sure he was surprised a bike rider caught up to him.
