RC big rigs on show in Germany

What is it about Germany that makes them so interested in these miniature things? They already have Miniatur Wunderland in Hamburg, and if I'm reading this video description clearly, this seems to be an entirely different one in Dortmund, Germany (I think it's temporary though).

But seriously, look at these trucks just drive by. It's not about speed. Just steady straight lines and super wide turns. And if you didn't see the giant people stepping over the sets every once in a while, you might just think these were real trucks. I want one of these.
