Fatal Car Accidents

Most of our country’s fatal car, truck and motorcycle accidents occur on rural roads, according to statistics released by the National Highway Traffic Safety Administration. Fifty-six percent of 37,261 traffic deaths occurred on rural roads during 2008. Researchers say that the higher death rate on rural roads stems from a combination of faster driving speeds, poorer road engineering, behavioral influences and slower delivery of acute medical care.

I would think you would have to add more single lane, curvy roads where vehicles are traveling at excessive speeds.
