Korea's smartphone zombies--a solution?

This Reuters video documents a new solution being proposed for South Korea's "smart phone zombies." I would only add a couple of points for context.   In practice, the rules of the road in Korea place very little stress on the "pedestrian has the right-of-way" which is so basic too driver education and related laws in the United States.  Second, my casual observation indicates that a very high percentage of pedestrians are multitasking -- texting, talking or doing something else on their smart phone while walking.   The statistics cited in the video on pedestrian casualties in traffic accidents should bring attention to this matter.
