In this photo taken Sept. 12, 2012, Sandy and Jerry Wiseman pose in the driveway with one of their two cars , in Schaumburg, Ill. Jerry Wiseman and his wife, Sandy, took refresher driving classes to help them stay safe behind the wheel for many more years. More older drivers are on the road, and they face a hodgepodge of state licensing rules that reflect scientific uncertainty and public angst over a growing question: How can we tell if it's time to give up the keys?
