That's exactly the issues that Dallas is going through right now. A few of the bikeshare companies (Ofo, Mobike) are Chinese companies that mass produce cheap bicycles and they don't really seem to care if the bikes get damaged/lost, so they are pretty careless about where and how they place them. I've personally witnessed one of the bikeshare trucks slowly driving down the street while someone in the back literally just threw bikes off the truck onto the sidewalk.

The bikeshare companies also currently seem to be using the method of spamming bikes everywhere and hoping they get used, rather than trying to place them where they are actually needed. There was a picture of one of the companies in Dallas placing bikes on the side of a highway, with no pedestrian access, no sidewalks, and nothing even resembling a bike lane. That's just dangerous.

Fortunately the city is starting to crack down on them a bit, but it's a real shame that these companies took a cool idea and are pretty much ruining it with their piss-poor execution.
