A 2008 television report features security camera footage of a dusty white Passat reversing at high speed and smashing into a 64-year-old grandmother. The Passat’s back wheels bounce up over her head and body. The driver, Zhao Xiao Cheng, stops the car for a moment then hits the gas, causing his front wheels to roll over the woman. Then Zhao shifts into drive, wheels grinding the woman into the pavement. Zhao is not done. Twice more he shifts back and forth between drive and reverse, each time thudding over the grandmother’s body. He then speeds away from her corpse.
