I couldn't agree more with Denise. When there's little space, or on tricky spots on the road, I drive about 2 feet INSIDE (left of) the line so the drivers definitely can't miss me. If I know there's a car behind me and the driver can't pass me because of incoming traffic on the other side, I'll move to the right side once it's clear that I've been seen (but before the driver becomes irritable).

If you're sticking too close to the right, not only you're less easy to see, but also it's easier for the drivers to think they can pass you without going in the other lane. When you are clearly in the right lane, it becomes obvious that they have to change lane.

On roads with shoulders, I sometimes ride on the car lane too, especially near intersections where I know many drivers make a right turn and will be tempted to pass me and turn right right in front of me because they underestimate my speed. By moving in their lane, I force them to wait for me to cross the intersection and they can make their turn after I'm gone. I do this as diligently as possible, avoiding to make drivers unhappy (because when they become unhappy they're dangerous to other cyclists)
