We can mention it in the drivers' handbook. There's information on using cell phones while driving on the DMV's website . And test it on the exam. Let me quote Patricia Pena, whose daughter was killed in a cell phone-related collision. I believe shame, we can also call it political correctness or peer pressure, is enormously effective but underutilized in many areas.
Shame fosters common sense.
Shame fosters community. By most objective measures, the Bay Area is home to some of the most neglected roads in the nation. In addition, Californians rank third in the nation in taxes per vehicle, but dead last when it comes to per capita spending on highways. When our roads are unsafe, the people who travel on those roads suffer property loss and personal injury. And if we want safer roads, our spending priorities on transportation have to change, but perhaps that is an issue for another hearing.
