Until you realize they are 4 times more likely to die in a car accident in China vs the USA. If you are just concerned about survivability, this isn’t a good bet.
Probably has to do with people not wearing seatbelts. I remember years ago the taxis had covers on back seats so you couldn't even reach the buckles. Then Shenzhen enforced belts on all seats and things got better there. I wonder if it spread to other cities.
There is more: bad roads, lack of traffic law enforcement, weird liability laws that make fatalities more appealing than injuries, lack of liability at all in many cases, etc...
