Hit-and-run is the characteristic crime of the rich in developing countries, which is why it's so often at the root of mass incidents in China - normally when the driver is stupid enough to try it near a crowd which can surround the car - and online outcries like "My father is Li Gang." It combines three defining features of the young rich - callousness, carelessness, and a love of big cars. That you can easily acquire a driving licence in China without ever having been behind the wheel of a car helps.
It hasn't yet had quite the influence it did in Nepal, where the penchant of young Nepalese royals for running people over was a serious contributor to the fall of the monarchy, particularly when the one-time Crown Prince (Paras, known for being a drunk and a fool, not Dipendra, who shot everyone - pleasant family) ran over one of the country's most popular singers.
But I'm surprised that this case (in which, for the link averse, a 21-year old knocked a woman off her bike, then stabbed her to death to prevent her taking down his license plate) hasn't caused more anger - perhaps because he was "caught" so promptly. Note he was arrested the same night (on a different charge) but "turned himself in to the police" two days later for the murder - i.e his parents spent two frantic days "negotiating" a deal that would partly protect him when it comes to sentencing. (There does seem to be some online furore about the probability he'll avoid the death penalty - you might also get the "suspended" death penalty, which is almost never implemented)
