På Stockholm

As a bicyclist how do you communicate in a constructive manner to a driver that just did something unsafe or illegal to you?

On my way to downtown Kirkland a man pulled out from the curb in front of me cutting me off. While I could have braked and cursed under my breath I decided to ride along the driver side so he could see that he had just cut me off. I was planning on doing the "what in the world are you doing look" but the "I can see you so why can't you see me look" came off. He only saw me after his two passengers said something. He slowed down and let me pass.

I don't want to come off as a dick but if I was going faster or he merged out faster we could have had a collision. Drivers need to get feedback when they do something wrong (a honk for example) but bikes don't have horns. So then bicyclist are left with hand gestures or yelling. Both of which don't really engage people. I guess what I'm saying is next time you have a conflict with someone on a bike try to engage them and understand, don't just assume they hate you.
