Chinese police are searching for a motorist caught on camera climbing out of his vehicle while speeding over a bridge.
The footage shows the man leaning out of his open-doored vehicle while steering it haphazardly through traffic.
"I was overtaken at high speed by a car with a young man in it playing music so loud it drowned out my radio," motorist Tian Lu said.
"Then as he got ahead he started to climb out of the door and clung onto the bodywork.
"He didn't slow down. If anything he went faster and zig-zagged in and out of the traffic," he added.
Chongqing police say that they are confident of finding the driver.
"We have his registration number thanks to other motorists and their photographs. He will be caught swiftly and punished severely," said a spokesperson.
