I heard that too, but I can't say I noticed it.
Same here. The shoulders may be a little narrower on the east side of the road, but to me the main issue is with the sightlines due to the topography. The east side (i.e. south-north side) frequently has a steep hill alongside while the west side has a dropoff to the coast. When going around a sharp curve to the right on the east side the cyclist is likely to be hidden from view of following traffic by the hill. OTOH, the cyclist heading south on the west side will generally be much more visible.
