If I am preparing to turn right in my car, I merge to the right edge of the lane to discourage cyclists from passing on my right.

If I am cycling, I stay away from the right side of the lane when approaching intersections. I pass right-turning traffic on the left. I don't pass traffic headed to the same direction. At red lights, I don't filter forward.

I understand that some people experience enough congestion that they feel tempted to filter forward, particularly to make a green light. This hasn't been enough of a concern on my commutes to bother. Sometimes I miss a green light due to the length of the traffic queue, but not very often, and not enough for me to consider invonveniencing drivers by making them overtake me more than once.
