Eight years ago, a 19-year-old college student in Utah was driving in the Rocky Mountains. His car jumped a divider and hit another car, causing an accident that killed two scientists on their way to work. The driver said he had no idea what happened, but phone records showed he was texting. The case was one of the first texting-while-driving accidents and helped spark state laws and a national awareness campaign. A New York Times journalist, who won a Pulitzer prize for his reporting on the use of cell phones while driving, is out with a new book about the accident. Matt Richtel argues texting while driving could be as dangerous as drunk driving, but may prove even harder to curb.
