"Double-hit cases" have been around for decades. I first heard of the "hit-to-kill" phenomenon in Taiwan in the mid-1990s when I was working there as an English teacher. A fellow teacher would drive us to classes. After one near-miss of a motorcyclist, he said, "If I hit someone, I'll hit him again and make sure he's dead." Enjoying my shock, he explained that in Taiwan, if you cripple a man, you pay for the injured person's care for a lifetime. But if you kill the person, you "only have to pay once, like a burial fee." He insisted he was serious—and that this was common.
Most people agree that the hit-to-kill phenomenon stems at least in part from perverse laws on victim compensation. 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. The Chinese press recently described how one disabled man received about $400,000 for the first 23 years of his care. Drivers who decide to hit-and-kill do so because killing is far more economical. Indeed, Zhao Xiao Cheng—the man caught on a security camera video driving over a grandmother five times—ended up paying only about $70,000 in compensation.
Security cameras have regularly captured drivers driving back and forth on top of victims to make sure that they are dead.
In 2010 in Xinyi, video captured a wealthy young man reversing his BMW X6 out of a parking spot. He hits a 3-year-old boy, knocking the child to the ground and rolling over his skull. The driver then shifts his BMW into drive and crushes the child again. Remarkably, the driver then gets out of the BMW, puts the vehicle in reverse, and guides it with his hand as he walks the vehicle backward over the boy's crumpled body. The man's foot is so close to the toddler's head that, if alive, the boy could have reached out and touched him. The driver then puts the BMW in drive again, running over the boy one last time as he drives away.
Here too, the driver was charged only with accidentally causing a person's death. (He claimed to have confused the boy with a cardboard box or trash bag.) Police rejected charges of murder and even of fleeing the scene of the crime, ignoring the fact that the driver ran over the boy's head as he sped away.'
