North Korea has unleashed the most technologically advanced traffic control system in the world. It is so advanced that it doesn't make any sense. The NK military now, apparently, can drop GPS-enabled traffic control circles with women attached to them by magnetic shoes to virtually anywhere is the world. From the video subtitles:
And by our dramatic demonstration of this traffic control capability, we wanted to show the world our superiority.
Of course, there isn't actually much traffic in North Korea to control, but we should be mindful of this major advance nonetheless.
