I am riding as far to the right as reasonably practicable, which is the Calif. Vehicle Code standard. Sometimes that means taking the lane, but usually it means riding in the right quarter of the lane. Due to narrow lane widths, an overtaking car will almost always need to move slightly (but not completely) into the next lane over to pass.
