Why do you think almost every major city has a subway? The number of people who need to move around in the city far exceeds the available road space, without public transit, the entire city would be clogged with traffic.
Even in a more meta sense, cities can and should be healthy places that are built on a human scale. Necessitating cars for everybody pollutes more than just the air. Tires and brakes wear down, leaving microplastics and heavy metals to be washed into rivers when it rains.
Noise pollution from cars makes cities unpleasant and the air quality creates worse health outcomes for the people living there.
Human societies have existed without cars for thousands of years, and we already have a way to traverse cities effectively that predates widespread adoption of personal vehicles, mass public transit.
