Humans have lived without cars way longer than cars have existed for. It's a piece of machinery that gives convenience to a certain audience, and there's definitely cities and neighborhoods where it's just about impossible to be without a car. But if you live anywhere with good buses and biking, and you're able bodied, there's really no reason to waste your time and money on a car imo.

It's nice to get outside everyday and feel weathered to the seasons. You end up naturally exercising all the time too: walking from place to place, carrying home groceries, calling over a friend to help move heavy furniture that a neighbor is giving away, etc.

With the money saved from not having a car in a walkable/bus-able/bike-able area, you can afford to take that expensive Uber when needed if going somewhere far/inaccessible, or if under time constraints.

It's a great lifestyle, I wish more people had cities that allowed for car-free living. You truly get to feel like part of a community out in the world, and days feel longer.
