Are the feces, shattered glass, and tent cities only a minor inconvenience to this person in a wheelchair?
If it's one thing entitled early adopters and east bay commuters have in common, it's that they DGAF about the sense of community in SF. So they park these things in the most selfish ways possible. I swear some of them have to be doing it on purpose. I've seen them blocking turn styles at embarcadero station before.
I had a friend visiting from out of state and usually the first criticism of SF I hear is something about homelessness as we pass through the 'loin. But this time we were by embarcadero and it was "did a scooter gang of children all get raptured at once?"
No, feces and shattered glass are not a major impediment; wheelchair tires can usually go over them, and additionally, area taken up by individual instances of feces on the street is measured in square inches, so wheelchairs can typically be navigated such that the wheels avoid touching them.
Yes, tent cities are also an impediment, which is why the city actively works to get rid of them, even implementing short-term solutions that do no good and possibly harm in the long run like having the police and community workers forcibly clear them. Not to mention the literal hundreds of millions of dollars a year the city spends on homeless programs, which is many, many orders of magnitude more than they’ve spent on any kind of regulation of scooters.
