We will never eliminate all accidents, but we can, over time, build better roads. If we make areas safer for pedestrians, cyclists can generally piggyback on that infrastructure. There's a new invention, called a "sidewalk," that would take care of a lot of the problem. Build the sidewalks wide enough and bikes can share with pedestrians in high trafic areas. On rural roads, make good shoulders a priority. It will save lives, mostly motorists'.
