The National Highway Traffic Safety Administration has produced a minutely detailed document addressing and attempting to assess driver distractions. According to its numbers, "17 percent (an estimated 899,000) of all police-reported crashes reportedly involved some type of driver distraction in 2010." Out of that number, three percent, or 26,000 accidents, were caused by distraction from "a device/control integral to the vehicle," such as a navigation or infotainment system.
