Basically for carrying goods, doing long drives, or comfort in bad weather. Public transport works well here but you can still end up having to do a lot of waiting and walking if you are doing a trip somewhere. Also the more connections a trip needs then the higher chance something can go wrong. For example, missing a train because the connection was late. There are car sharing services here too, and there is one of these cars right next to my house. I would rent that when I wanted to go to an appointment somewhere. But there were enough times that the service was unreliable or booked out when I needed a car urgently, that I got annoyed and decided to get my own car. I think a mix of cycling, public transport and having your own car is best.

Pretty handy to have a car. I have one too, for the first time in 10 years. But I don't use it to commute and I actively try to avoid using it.

But sometimes you need to take the wife and kids to visit some family out of town or go down to the local hardware store to pick to materials. There's a lot use usecases
