I saw several of them in more remote areas like the fränkische Schweiz
and the Altmühltal (Nürnberg area).
When I ride a motorbike I don't get a lot more information than that I'm
actually on a road (but no road or village names or such) - it's too
cumbersome to take such notes on a motorbike.
As I often saw these untagged "segment chains" done also by someone
else, I thought that's how to map streets when you don't know much more
about it. I could imagine that's the cause for a lot of those segments!
As I know now, it's much better to way them and tag them as
highway=unclassified than to leave them as "raw chained" segments -
which I formerly did. As I'll ride these areas repeatingly at the
weekends, I'm going to "wayify" them as I go - but that'll obviously
will take some time (probably months or even more to get them all).
So please don't delete such segments, it'll save me a lot of work ...
P.S: That's just another example, that we don't take the newbie by the
hand and tell him exactly what to do. Instead, we just say: Have a look
at the Wiki for the tag list and do it yourself - and leave him "in the
dark". It's a lot better to give precise examples and let the user
decide - with good reasons - to do it differently (there's already some
effort to improve this). Otherwise, a lot of diverse things will happen
which is then what's not really helpful in the long run and leave to a
lot such "artefacts" :-)
