You're right about the Snopes article. It does do a decent job of pointing out that a lot of this reporting is rumor based.

This first anecdote (also highlighted by Snopes) is amusing

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.

So is it Taiwan or the mainland with these wild laws?

Another false claim about China, it seems.
