Yes, the _majority_ probably is parked properly. But there are so many cases of "bike abuse" around that I see on a daily basis that I'm constantly shaking my head about this lack of respect and care. Is DC that much worse? I wouldn't know.
But people are people and some things are quite normal and expected here.. Like randomly putting these bikes ~wherever~ or littering cigarette buds.
Even if the majority are using the service properly it takes seeing one bike in a tree to ruin the system for everyone.

The city has been extending and building protected bike lanes like crazy too.
I've seen everything from daily travelers to huge groups (20+) of tourists riding them.
I can't comment on DC's dockless bike share, as I haven't seen it myself. I wonder why it's working so well over here and not over there?
It's definitely a culture thing. In Sydney people seem to think it's fun to trash the bikes, throw them in rivers or just render them unusable.
It might be a culture thing, but looking at the comments here it seems to occur in every city.
Not a specific city problem, a humanity problem.
