Yes - An unclassified road is a road which does not have any
classification. As does a residential not have a classification.
"Unclassified roads have lower importance in the road network
than tertiary roads, and are not residential streets or
agricultural tracks."
Lower importance than tertiary - NOT residential. No word about
beeing of higher importance than residential.
When you continue reading the distinction is that you MAY use an
unclassified in city limits when there is no residential usage.
"Public roads of low importance within town and cities that are not
residential may also be highway=unclassified."
For me this means that 99% of the roads within city boundarys cant
be unclassified because there is residential usage.

Why not? This enables a routing engine to assume different
characteristics of roads.

Have you had a look at the original example images for an unclassified?

I would not expect more traffic here - I'd expect less.

Not in my reality and not in the original OSMs reality. Yes - through
misleading statements in the German article this might have influenced
at least the German community to assume otherwise - This is why
i request clarification.

The region where i map mostly we agreed that we may tag roads with clear
interconnecting character and wider lanes with one class higher than
they would have by assuming the strict classification. We agreed
that the causes by which we tag higher be placed in a note= tag on
the road.
So a large wide interconnecting road within city limits might be
a tertiary.

My knowledge and usage predates the German Forum by years - I was astonished
finding statements in the German article for unclassified which do not match
(but oppose) the English versions which i typically use and prefer.
Its not the first time i find the German articles to contain a hidden
agenda bei a minority or single mappers trying to steer the community.
