A driving teacher in China is using an unorthodox method to get his students to drive with more care. He calls it the “fatal blow” method. Basically, students have to manoeuvre the car with skill or risk crushing their smartphones... or those of their classmates.

An amateur video documenting this unique technique was posted on April 10 on the Beijing Time YouTube channel. It was filmed at “Jade horse” driving school in Dezhou, a town located 300 kilometres south of Beijing in China’s Shandong province.
