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.
This phenomenon is caused by the incentives facing a driver:
In China the compensation for killing a victim in a traffic accident is relatively small—amounts typically range from $30,000 to $50,000—and once payment is made, the matter is over. By contrast, paying for lifetime care for a disabled survivor can run into the millions.
In other words, once you hit a pedestrian, the marginal benefit of killing the pedestrian is positive.
