I may have actually flipped drivers off in almost every province. The funniest thing, which you mention, is watching the expressions of those on the receiving end. Most of the time they don't even realize they've done something wrong and so just look genuinely surprised.

Once in Tibet, I was stopped at a checkpoint with a driver that had previously cut me off on a blind turn at high speeds on a mountain road earlier on. I walked over to him in my full riding gear, front of the helmet flipped up, and confronted him about it. He was so surprised to be on the receiving end of a scolding from a foreigner on a motorcycle that he didn't know what to say. When I asked why he passed me on the blind turn, he just said, wide eyed, 'bu zhi dao' 'I don't know." After a bit more scolding I eventually turned to walk away and head back to my bike. At this point the driver finally seemed to have gathered his wits about him and he yelled back at me, "You were going too fast!" to which I responded "YOU passed ME!" and that was the end of that.

Nice write up. Thanks for sharing!

Keep the paint side up and the rubber on the road ;)
