The car-centric culture of many places (especially the US, but it does apply in basically all of the industrialised world to varying degrees) is due to infrastructural factors. If a country is designed to be navigated by car, then you need a car to participate in that society. That’s why people want cars.

Things like the freedom of having a car are also from social factors. A lot of people learn to drive as teenagers, and want to escape the patriarchal environment of the family, hence a car provides freedom. In a world where children are socially raised and the family is abolished, teenagers don’t seek to escape from the family. And, of course, a car can be a way of providing freedom because other means of freedom of movement don’t exist—a lack of accommodation for disabled people to get around, a lack of public transport and safe cycle routes, etc.

Most people wouldn’t want to give up their car for those reasons. If we just got rid of all cars without addressing any of these issues, I’m sure most people would be unhappy about it. So if that’s what you’re suggesting, plenty of people do stand to lose. But if we address the issues that make cars the only option for a lot of people, I don’t think the average person would care. Car enthusiasts can still have their cars, but it becomes a hobby or lifestyle choice, like people who have a boat. And car haters would most certainly be a lot happier too.
