Not owning a personal vehicle is only okay if you live in the heart of a city …
Like most people in the western world (and indeed likely in most of the world) do.
… and don’t go outside of that little bubble.
Because rental of smaller vehicle services (like taxis, etc.) is totally not a thing.
The problem here is that you have the American disease (even if you're not American). You're so infused with the cultural insistence that there's only one way to do things … the way things are done now … that you literally cannot conceive of a life without cars (or guns, or with public health care). Despite this being, you know, the norm for most of the world.
