Does this make any sense?

funny, weird signs on the ground. reminded me of a song written by nico:

...

Now that I'm almost not so very far behind - I want to know do
I stay or do I go - And maybe follow another sign - Now that I can
Now that it's easy, ever easy all around - Now that I'm here -
Now that I'm falling to the sunlights and a song - I want to know
do I stay or do I go - And do I have to do just one - And can
I choose again if I should lose the reason ?
...

anyway...what does these signs mean? that you should not park your
car directly in front of the garage but nearby? and which car is so small
that it can stay there? next question: should you drive that close to
the wall? i found it very amusing and i also like the camera ...
