Amusing footage has emerged from China of a BMW driver being rescued from his submerged car after he accidentally pressed the accelerator and ended up speeding into a river.

The video, filmed in Jiaxing, Zhejiang Province on Wednesday, shows a man, speaking on the phone, climbing out of his sunroof and being rescued by an elderly man with a boat.

According to local reports, the unlucky driver's shoelace got caught around the accelerator pedal, and the car ploughed into the water.

Fortunately, he wasn't injured and, by all accounts, remained relatively calm.
