Maybe I should say that pedestrians should count, because evidence from a recent walk bring me to conclude they don't actually count at all. In one short stretch of a busy street, trying to walk on the sidewalk, I was confronted by someone whose yard waste took up the entire sidewalk all along the front of their house:
one homeowner with not nearly as much brush but who just as effectively blocked the sidewalk:
and yet another whose lovely plantings encroach so far into the sidewalk area that there's barely room for one person to walk there safely with no median to separate the walker from the traffic:
I've known people like this. I had a next door neighbor once who had her "yard man" move my bags off my lawn and into the street. I moved them back. After she had him move them again I talked to her about how it's illegal to pile the yard waste in the street where it blocks the gutters. She had him move the bags onto the sidewalk. *sigh* I told her that blocking the sidewalk was also not allowed. She said, "But it will kill your grass." I assured her that I didn't mind, that if the grass died it would grow back.
Now here's the telling part: She said, "But I can see it from my window, and it looks ugly." It was all about her and what she wanted.
Such a self-centered mindset is hard to imagine, but there it is; and my experiences walking show that she is not alone.
