I got pulled out on today going by a school. A car inched out, blocking the bike lane trying to see around another car to turn right. From a few yards away he looks right at me and proceeds to go. I immediately took the lane, with him on my right; pointing him down to stop in the bike lane as I rode by. The second I got back in the bike lane another car was randomly stopped right in front of me to let their kid out. I had to retake the lane, right in front of the guy I just passed (before he started accelerating). As I proceeded through the obstacle I gave a gentle knuckle knock to the front corner panel of the stopped car. That's my customary way of 'honking' at vehicles that are creating a dangerous situation for cyclists.
