quite common. I drive in china about 2-3 times a week and I'm ashamed to say but that's what I would see on a monthly basis. Just straight up assholes driving without the care for others. Backing up on a highway, driving in the wrong direction on a highway, driving on the shoulder, high beams 24/7, speed limit 100km, drives 60 because he/she is on the phone and cant fucking multitask, switching lanes without even checking or blinking, can't pick a lane, miss an exit on highway then backs up.
I've driven in a lot of countries and this is by far the most fucked up especially with the amount of cars on the streets and an infinite amount of assholes.
If you want to learn how to drive like a ass, this is the place to be. Possibilities are endless, its like reckless driving without consequences.
