Sure. Let's begin with Matej's example: route 7 on Sulec, Czechia.
It's not continuous in OSM, but it is in Google Maps, Here.com and
- https://www.openstreetmap.org/#map=14/50.3083/13.8837
- https://www.google.com.br/maps/@50.30831134,13.88367320,14z
- https://wego.here.com/?map=50.30828,13.88449,14,normal

In Germany, there are many small stretches of trunk in the area
between Berlin, Hamburg and Hannover. On the route Hamburg - Uelzen -
Braunschweig, it happens twice along route B4:
- in Uelzen: https://www.openstreetmap.org/#map=13/52.9611/10.5890
- in Gifhorn: https://www.openstreetmap.org/#map=13/52.4694/10.5244

No such changes in Google Maps, Here.com or Waze.

In Openstreetmap.de, this leads to the interesting effect of knowing
where the road is divided. However, that does not translate well
elsewhere - for example, in England, on route A40 between Oxford and
Gloucester, which is not divided:

In Italy, on route SS12 between Verona and Modena, it also happens twice:
- in Isolda della Scala: https://www.openstreetmap.org/#map=13/45.2730/11.0218
- in Mirandola: https://www.openstreetmap.org/#map=13/44.8679/11.0485

As in the other example, no such changes in Google Maps, Here.com or Waze.
