I don't have a car. Everything's so convenient here. There are two metro stations within 5 minutes of my house. If the metro doesn't go there, I'll get a taxi. If I need to bring something big home from Ikea, there's an app where you can hire a man with a van within 10 minutes. And then occasionally I'll hire a car if I fancy going somewhere on holiday that doesn't have decent public transport. All of that is way cheaper than owning a car, and the few times I have rented a car to do something in the City, I've regretted it because I've spent way more time say in traffic than I would have done on the train.
Having said that, I don't have kids, and I imagine that could change things.
