You're an American, so I assume you have only ever heard of public transport, and certainly do not experience a semi-reliable public transportation system on an everyday basis.
This perception is strongly coloring your view of how people ought to move from place to place.
I'm not a Londoner, but I live in a European city with rather decent public transportation, and literally the only time I needed a car at all is when I was moving into a new apartment - and even then I could have just hired a company to do that for me if I hadn't been short on cash due to the brief, COVID related breakdown of my primary income source.
