SMARTPHONE APP WARNS PEDESTRIANS OF ONCOMING CARS: “The app relies on machine-learning and image-recognition algorithms to identify the fronts and backs of vehicles, and takes into account varying light conditions, phone tilt, and blur. When WalkSafe detects a car approaching at 30 miles per hour or faster, it vibrates the phone and makes a sound to alert the distracted user.”

UPDATE: Reader J.R. Ott writes: “We wonder why people are underemployed and unable to meet tough goals. Hell they can no longer walk by themselves without a gadget. Heaven help them if the battery dies, they will collapse on the sidewalk sucking their thumb crying.”
