Cyclists are not obligated to ride on the shoulder of the road for your benefit. When they do that, they do that as a courtesy, FOR YOU.
Bicycles are vehicles under the vehicle code. READ THE VEHICLE CODE; it will tell you explicitly that the shoulder of the road IS NOT for moving vehicles. If you come around a curve and kill a cyclist, you'll be guilty of vehicular homicide, and your belief that cyclists are required to accommodate your poor driving skills will not keep you out of prison.
All I’m saying is that three objects (two heavy machines at speed and one bicycle) cannot occupy the same physical space simultaneously. Driving a wide truck on a narrow road around a blind curve in the mountains only to be surprised by an oncoming vehicle on the left and bicycle riding the stripe will be a very ugly collision and the biker will lose that battle even if he ‘only’ gets smacked with a mirror. The only one with room to maneuver is the bike.
