Take the taxi model, eliminate the driver, and there it is. There are plenty of cities in the world where taxis are more ubiquitous and owning personal cars are very expensive (parking being a big expense, but also winning the license plate lottery). American centrism doesn't really explain it.

So you normally don't take a taxi out of the city, and it is such a niche activity that I'd assume that it would be a different kind of speciality business with much higher costs that allow it to solve these problems. E.g. Private parking lots like those today.
