It's worse now that Lime and other bicycle rental startups have littered the sidewalks with bicycles. When I'm not running around a bike left on the sidewalk, I'm getting run over by somebody riding one on the sidewalk.

I'm amazed at how often a bicycle rider on the sidewalk will actually warn me to get out of the way. I haven't knocked anybody off of one yet. It's only a matter of time before somebody bumps into me on one and gets hurt.
