Usually, that is the best way. But, on some roads where there isn't enough
room on the right side for a cyclist to ride, and for a car to pass them
without at least partially crossing the centerline, it is safer for the
cyclist to get out in the road. People will literally nudge you with their
rear view mirrors in an attempt to pass you without crossing the
centerline. I've had it happen. When the road is too narrow, I'd rather
have people waiting behind me for a couple of seconds while I round the
curve than be pushed into the ditch by an impatient driver.

Yeah, good point.
