Apple Thoughts: Are Your Surroundings Lethal?

"A Lethal app for your iPhone! OK, the headline is a bit misleading. This app won't kill you; in fact, it's designed to inform you about dangerous situations in your vicinity."

Lethal bases your danger level on several geographical factors (lethal wildlife, crime, disease, and disaster probabilities), and lets you know the best option, ie get out now! I wonder if it factors in that the use of this diverts your attention to your surroundings, so if there was something dangerous coming your way, you might not know it until too late?
