Not many news outlets picked this up - only the Segye Ilbo and JTBC - but JTBC offers video of its news report titled "More 'retaliatory driving' - foreign instructor chases and assaults car that cut him off." Said 40ish instructor, who works at an English hagwon in Gangnam, was driving a scooter two weeks ago when he was cut off by Mr. Jo, who was driving a car, and in retaliation he chased Mr. Jo for a kilometer and then cut in front of him when traffic was reduced to a single lane and stopped, forcing Mr. Jo to stop. He then walked up to Mr. Jo's car, and according to the report, hit him in the face, and then gave him the finger before driving off. [The Segye Ilbo adds that he hit him twice through the open window.] He was booked without detention for assault and property damage. Needless to say, when so many cars have cameras running in them, letting your anger get the better of you has become an even worse idea than it was previously.
