Spent the last 6 months in Seoul and the surrounding cities in Korea. Never needed a car. You can literally do everything without a car, everything is a short walk. I truly believe it makes a huge positive impact on happiness when you can just walk anywhere instead of having to drive. Also you'll notice that in Korea/Japan there are way more small businesses and things to do (eg. karaoke, cafes, etc) because people of this. In America there's relatively less to do because leaving the home is more of a hassle and less interesting, so people just stay in more.
My least favorite thing about living in America is the dependence on cars (outside of a select few cities like NYC). Now that my parents in the suburbs sold their spare car, whenever I go back to visit, I'm stranded there during the weekdays because the nearest bus stop is like a 40 minute walk, and the nearest subway would be maybe a 90 minute walk. If I need to go anywhere, I'm dependent on Uber/Lyft. Even if I get access to a car, there's relatively much less to do as I mentioned above.
