I don't believe that laws are responsible for this plateau in distracted driving, but instead the fact that hands-free phone integration in new cars became pretty common six or so years ago. So now, even people buying used cars are buying cars that have hands-free usage. My two cars from 2013 the barest base models available of already cheap cars and they both have hands-free support. The graph showing the downward trend in distracted driving starting at ~2013 is solid evidence in favor of this explanation. If laws were responsible for the reductions, then the article should point out that states who didn't pass new laws also didn't see reductions in usage. I do agree that this is a problem, but misidentifying the cause of the downward trend is actively working against a solution. Perhaps we should be passing laws that mandate vehicle-phone integration standards rather than punitive traffic laws.
