Glad to see you came out relatively unscathed and that insurance will cover everything. Was the truck driver given a citation or did you not report this to the police? When I was on South Korea, traffic seemed pretty dense and crazy. I think I only saw one or two people in Seoul actually on a bike although I did see a few bikelanes. I saw quite a few more people on bikes in Suwon but then again, the traffic there didn't seem as bad.
BTW, I'm moving this thread to Advocacy & Safety.
