I always pull as far forward as I can, like to the front of the crosswalk, while remaining about in line with the painted bike lane. That far forward, there is always room for people to right turn behind me, because the curb curves away well before it gets up to me. Still, I more often find timid drivers waiting, and I try to wave them through, let them know, yes I see you, yes I'm fine with you going through, thanks for thinking of me.
