> I don't think there's any healthy level of private cars coexisting with humans in a city

Concentrating humans together into a small locality, which is what a city is, will inherently have a significant environmental impact. Cities before private cars were still quite polluted, because transportation still has to take place just to keep the city running. Electric vehicles are the best-case scenario for truck deliveries, construction vehicles, and everything else you need to keep a city running on a day-to-day basis.

Moreover, you have to consider all cities in this analysis, not just posh, post-industrial cities like those in the US and Western Europe. Manufacturing has to take place somewhere, and logistics considerations imply that most manufacturing will be located next to transportation infrastructure. Just like any other economic activity, manufacturing benefits from talent clusters (a major reason cities exist), so manufacturing will tend to concentrate in cities as well, or at least the suburbs, which you can easily observe in China.

If you really hate air pollution, move to the country and be willing to sacrifice the advantages of cities.

Cities have a positive environmental impact when you compare it with spreading the same population in villages across thousands of miles.

It would be an insane amount of roads, cabling, water pipes, etc.

Cities are bad for human health, but good for the environment.

Are they bad for human health compared to other ways of living like rural or suburbs? iirc rural people get the least amount of exercise because you just sit inside all day.

… in the US and Canada.

when we lived in the suburbs my family and i spent way more time inside than we do now in a rural setting. i think maybe you got mixed up. rural people are generally very active.

i really do hate air pollution! it drove me away from idaho, where 2-3 months of the year massive forest fires would choke the air and force everyone inside (gave my kids asthma).

we recently moved away from a suburb near two highways, out to a rural area where we are half a mile from the nearest paved road.

besides the lowered air pollution, the lower noise pollution is a huge benefit. hearing birds instead of traffic is amazing. and my kids don’t choke in their sleep any more!
