We have got some here in Sweden with two "harmonicas" I don't know the word for it in English...
Here is one, don't know where this is from though:

Talking about that, you don't wanna be in the rear part of this articulated bus:

A guy at work told me that his mom drove one of these in Gothenburg and that they could lock the rear part so it wouldn't swing out like that, if it would start drift in the snow or such.
Nice pictures btw, Animatronixx
