I agree with the previous statements about a difference in driving culture, but would still like to post an answer. (Hopefully, the objective, informed answers will eventually outnumber the racist-a*s "slanty-eyes" responses on this question...)
I am an American driver living in China right now, and I 've gotta tell you, I have nothing but the utmost respect for Chinese taxi drivers! They're like fighter pilots with all the fancy maneuvers and avoidance techniques. Many taxi's aren't equipped with seat belts, and that really worried me when I first moved here, but now that I've seen the amazing skill of the taxi drivers here, I can relax knowing that I'm safe in their car. They will not hit anything, or allow themsleves to be hit by another vehicle.
You have NO IDEA how many f*cking people, bikes, carts, dogs, donkeys, busses, trucks and other sh#t are on the roads in China, and let me tell you: an American driver (anal-retentive, must-follow-the-rules, stay-within-the-lines, right-of-way-no-speeding, don't-enter-on-yellow, wussy-b*tches) wouldn't last two SECONDS on the roads in China. You gotta have BALLS to drive in this country, man!
It is impossible to follow the traffic rules here, because no-one else does. The one sorry bastard who tries to follow the rules, or stay in the lane, or stop on yellow, (whatever) will literally be plowed over by masses of car tires, feet, wheels, hooves and paws, and never get to where they're going.
So, in short, Chinese drivers are very good at what they do (you have to be here), and when they come to America and get behind the wheel, they use their offensive-driving tactics and reflexes to get where they're going. Think about it, if you were trained to drive in the same environment as they were, it would be very difficult to shake the habit of "must-get-there-first, go-go-go-swerve! there's my chance-go!" that they instinctively assume when driving.
I do, however, also firmly believe in the "When in Rome..." philosophy, and think that Chinese people who want to drive in America need to familiarize themselves with OUR rules, and try their best to study our defensive-driving tactics in order to prevent accidents. Because Americans just don't expect people to drive like that, and might not be able to avoid a Kung-fu driver move.
I am learning to drive the Chinese way, and have seriously had to grow a set of cojones just in order to park the car! If I drove the American way here, I would be the one causing accidents, because people behind me wouldn't expect me to suddenly wussy-out and stop to yeild for anything.
I hope my answer will be read, and will help people better understand the "Chinese driver" (I prefer "Everybody was Kung-fu driveaayying"...ha!) phenomenon in America.
Peace!
