I try to spend as little time as possible sandwiched between tail pipes for obvious health reasons.
In a situation where there is sufficient space/time I filter around vehicles on the left. I hate passing on the right since I have seen motorists suddenly decide to turn on the red far too often. I'll pass on the right in a parking lot situation but if I am coming up on an intersection I will always attempt to insert into the lane prior to the intersection.
