The Japanese mobile carrier NTT Docomo has been producing a series of public service announcements cautioning people that using a smartphone while walking isn't a good idea. The latest video shows what happens when 1,500 people all do it at once. At one of the busiest intersections in Japan.
That's Shibuya crossing in Tokyo, a five-points intersection that permits "scramble crossing," which is everyone may cross in any direction, all at once. Assuming everyone tried to navigate this intersection while gazing down at a smartphone, NTT Docomo presents this madhouse scenario with help from Aichi University.
The moral of the story: Don't text and walk. And don't text and drive either.
