BogenDorpher writes "In a recent study by the Governors Highway Safety Association (PDF), driving distractions such as cell phones and other electronic devices cause as much as 25% of all US car accidents. It is common knowledge that driving while distracted is not a safe thing to do, but now we have some scientific data that goes in-depth on the topic. From the article: '"Despite all that has been written about driver distraction, there is still a lot that we do not know. Much of the research is incomplete or contradictory. Clearly, more studies need to be done addressing both the scope of the problem and how to effectively address it," said GHSA Executive Director Barbara Harsha.'"
