OP, the problem with your riding line is that you are on the left side of the right turn lane. You should be on the right side of the turn lane, somewhere between the middle of the lane and the redge. When roads are bad, the best line is about where the passenger side wheels run. I usually run just a few inches to the right of the right wheel and don't have trouble with cars racing past me or too much gravel in the road. [Now riding on the shoulder, or in "bike lanes" asks for a ton of gravel]
