These lanes and pull outs aren't common everywhere. When I visited NZ, it took me a day or two to realize they had a purpose. RVers usually are not driving in their home country.

I just recently tried to use the side lane in DK to let others pass (set signal, decelerate, pull over as far as possible). It actually confused the other drivers so much that they didn't dare to take over, even when there was lots of space to do so.

They’re all over the western US, very frequently with several signs notifying drivers that one is coming up.

I never seen those in the US or Canada... I've been mostly on the east coast though

Seconded, I was really confused until I watched a video shared. Never seen one of those in my life and I've done a lot of back road driving on the east coast. Typically we'll just have labeled passing zones.
