I think this is from China, could be Japan maybe ... wherever, it's still creepy.

This guy apparently doesn't care for tailgating.  (He also sort of reminds me of an asian Michael Myers.  He's even got cool "I'm going to strangle you before I impale you on some nearby item and then throw you under a passing bus" gloves.)

Anyway, if you're ever driving through some city in the orient; don't tailgate black sedans!!

That's just weird.  This, it would appear, was the second part of the story, here's some footage taken prior to the standoff.  (Is the orient like Russia? Where everyone has a dashcam for no apparent reason??)
