You know, after watching a few more times, the impact was more of clipping the side of the truck than smashing dead on. I've had worse crashes on bmx bikes than that. Anyone who rides bmx would probably agree too. I think he just got lucky, not because he's chuck norris tough.
Maybe it's just their culture but I've always been confused when accidents like these happen in Asian countries. The videos always show people just kind of going on about their business. Are accidents like this that commonplace?
