Distracted driving continues to pose a major safety risk across the United States, and it's a problem that can't be solved through legislation alone. That's the argument a pair of researchers from West Virginia University made earlier this month, in an essay published in the Journal of the American Medical Association. According to co-author Dr. Jeffrey Coben, the issue stems from two converging phenomena: a proliferation of mobile technology that has only amplified the risks associated with calling or texting while driving, and state-legislated bans that, while well-intentioned, remain difficult to enforce. Coben's proposed solution? In-car technology that would render cellphones inoperable.
