I find these very upsetting to encounter as I wander about town. If I were a writer of fiction, I'd make up stories about them.
Bicycle down. Still intact as far as I can see, but how long will it remain that way?
This is more serious. As an urban driver who must part in small spots, I approach pulling into a space next to a scooter with terror. Just a nudge could knock the thing over. Perhaps that happened here.
This one was a bigger target -- could foul play have been involved?
This looks like a classic story line. Megaton monster meets slight object, apparently glued, not embedded, in concrete. But why hasn't someone moved it away from the curb or even walked off with it? I didn't do anything either.
