I was doing my job as a police officer, patrolling the less-crowded streets of Seoul on traffic duty in my car, my radio quiet as I kept on lookout for any reason to approach drivers or pedestrians on the paths.

It wasn’t until I saw a regular, average looking car pull out from a corner I was driving at the speed limit at, without their headlights on, and well over the limit, that I turned my lights on, signalling for the speeding driver to pull over, matching their speed to catch up.
