A Very Unexpected Thing I Saw

I get a feeling people really enjoy my little riddles, so I’ll post another one.

Yesterday, I left the building where my office is located and, as usual, headed to the bus stop. There, I saw something really unexpected. Something that you never ever see around this small town and the neighboring tiny towns. This something is a symbol of civilization, freedom and efficiency for me. It always allowed me, as an autistic, to be an equal and productive member of society until I moved here and became deprived of this wonderful advance of human civilization. The moment I saw it, I started snapping photos of it like crazy. Maybe I’ll put one up on the wall of my office to remind me that somewhere, in big cities, civilization still exists.

Can anybody guess what it was that I saw?

And then later I’ll post a photo.
