Which is also, to some extent, the reality in the US as well. Some number of the "city centers" have better public transport and/or walk-ability [1] available than what is available just outside those city centers.
One big difference in the US is the massive land area difference as compared to Europe means there is a huge amount more land area (and therefore population) with little to no public transport or walk-ability available and a car becomes mandatory rather than optional in those areas.
[1] It's not perfect, I'm sure there are plenty of city centers in western states where even the city center itself is so spread out that walk-ability suffers and that a car tends to become more necessary.
Which is the same in small European towns and villages, there are only a couple of buses, many of which stop around 8 PM, and tend to occur once an hour in most cases, if not less.
Basic stuff like taking kids to school requires having a car, or being lucky to have some kind of Bus service collecting the kids, for some school levels, and doesn't cover stuff like taking them to other after school activities.
Want to go to the big commercial surfaces? They are all outside the town center and seldom have bus connections.
And many other possible examples.
