I could tell you about the years I lived in Houston or Los Angeles if you prefer. The situation for pedestrians there was not any better. I've also, more relevant to this article, spent a little time in Raleigh, though I haven't lived there. There is about a 2 block by 8 block area of downtown Raleigh that is reasonably safe for pedestrians.
Maybe somewhere like Portland is different; I haven't been there.
