I agree that cars are not good for cities. When I was in S. Korea few years ago, I got to visit a newer apartment complex, with dozens of 20 - 30 stories tall apartment buildings. One important feature the builder/architect added is underground parking for all cars of visitors/residents. The entrance to the parking lot is right next to the street.

There are roads within the complex for Fire/emergency/moving-trucks, but no other cars are allowed onto the ground of the complex. So there are no cars driving around within the complex.

Not having to worry about dodging cars or dealing with car-noise/engine-exhaust-smell all combined to make the quality of life so much better. With some grass and greenery planted, walking within the complex felt like walking on a hiking trail. And this is in the of a huge apartment complex with thousands of units.
