By the time you've focused on the map and your brain has decoded what you're looking at you've traveled far enough to be sliding on gravel or go careening into the side of a car. What's needed is a way that you can get directions from your smartphone without having to lose your focus and possibly your life and Hammerhead Navigation have one of the most interesting answers I've seen."
