Small country side roads routinely lack a central line in Sweden. Even smaller roads can lack the side lines too. And I'm talking asphalt roads here still. The same happens on many residential streets in towns and cities.

But sure, it would be rare to have a large road or street without markings. But most roads aren't large. Most travelled kilometers happen on large roads, but that is not the same thing as most roads. And many individual journeys would involve at least a little bit of small roads at the beginning, end or both.

And of course, if they are covered with snow and ice during the winter you can't see the markings anyway.
