At a maximum 30kpm, it should only take you about eight hours to drive north to Seoul. You drive along the shoulder of the highway so faster cars can pass. A couple hours in, you encounter a long convoy of tractors and other agricultural vehicles, maybe 1000 of them. As you overtake them, the driver of one tractor calls out to you, "Hey friend, where are you headed?"
"Choi Soon-sil said she committed a capital crime and deserves to die," you say. "I'm going up to Seoul to give her a hand."
"So are we," says the farmer, "though our methods are considerably less violent than yours. Care to join forces?"
