It's distracting enough sometimes to look at your personal nav device and watch the road at the same time. But this new augmented reality app from Route 66 has added another element that may further throw drivers off course. The app shows drivers the way by placing a vehicle graphically superimposed onto the road network of the navigation device. You follow the vehicle along the path just like you might follow a friend who knows the way. However, to me this is a recipe for disaster. You need to watch the "real" car in front of you not the graphic. See the video below and see if you agree.
