Thanks for the feedback folks. I think I'm going to just let it drop at this point. I really don't see an upside even with an off the record chat with the driver or a supervisor. If he did it on purpose, my calling him out won't change his feelings on bikes in the road and he'll continue this behavior. If he did it unintentionally due to being distracted it could result in a mark on his record which I will be blamed for and possible retaliated against. It's just not worth it.
