Earlier quoted context omitted.
How does it compare to other countries, though? 4000 is high, but it's out of 1400000000.
I think this perfectly illustrates the difference between you and me. You think there is nothing wrong with the untimely death of literally thousands of people because there are millions more who look just like them. I expect more of humanity.
We should try to bring that number (4000 or 40) down but if it's happens to be a very unlikely cause of death, maybe we should focus on more pressing things. Not ignore the 4000 (out of 1.4 billion), of course, just put it in perspective. I'm sure much more people in China die from other easily-preventable deaths. Road-related deaths are much more graphic and frightening than deaths from things like the quality of our food and water, contaminants in paints and construction materials, air pollution, infections, diabetes, cancer and so on. Most such deaths are not graphic, you won't see them on kaotic, but are usually far longer, painful and disturbing for the person and family.
To offer a personal rebuttal to you saying I don't care about those people as there are many that look like them, I love the saying "if you help a stray animal, you won't make a dent in the whole situation of helpless stray animals but you'll have changed that animal's life completely". So yes, 1 person or animal matters a lot. I've moved snails from the sidewalk back into the grass so they don't get stepped on. Likely billions of snails are getting crushed every year and what I do is not sustainable, but I still do it.
