I always take the lane in intersections and wait my turn in the line of cars just as if I were a car (unless I'm turning right). I've found that the drivers around here treat me better if I do that. Maybe they figure if I'm behaving like a car, they should treat me like a car and give me the same room and courtesy they'd give a car?

Also, many of the bike lanes in my end of Seattle "disappear" before intersections to force bikes to take their appropriate lane before the intersection. I think this trains the drivers to watch for bikes coming into the lane at intersections to some extent.
