As I said in another thread, the instructor makes it sound easy to just move out of the bike lane when passing parked cars, maybe in a more bike friendly town than mine. My experience is that the majority of local motorists do not understand why you're not riding in the bike lane that they seem to feel that their hard earned tax dollars have provided.
I will ride on or near the inner white line of a bike lane, and only move out of it if there's an obvious obstruction/vehicle intrusion in the bike lane. I find this method more suitable for my needs, than trying to educate the hundreds of motorists that I interact with daily. When there's no bike lane present, I usually ride in the right tire track or more center depending on the roadway's width. It's interesting to see the difference in motorists' attitudes when there's a bike lane present than when there is not one.
