Well, it seems limited to streets for the most part.
And presumably sidewalks!
I was working up a crack about how clearly the problem is intersections and that a system of mid-block passageways through buildings was clearly the solution, but then I clicked through to the actual map and it turns out that the maps normalized to "nearest intersection", which ruins that joke.
Just a couple dozen feet off the ground and you're almost completely safe.
Watch out for the Muni wires.
Of the ground my ass. To the left.
One important number is missing in the figure: The number of cyclists/pedestrians which pass the marked spots. Without that number it's not really possible to say which place is more dangerous than others.
But it's a nice map. I'd like to see something like that for Berlin. About a year ago the Berlin Senate started an interesting survey asking cyclists to name and discuss the most difficult cycling spots in the city. That resulted a really interesting discussion together with a map showing all the discussed spots: https://radsicherheit.berlin.de/diskussion (which takes a few seconds to load the overlay)
And hopefully there'll be improvements based on the discussion.
Maybe that kind of feedback would help SF city planners and also cyclists and motorists to get a feeling about the trouble spots.
I never felt at all unsafe biking in car lanes, but people would honk at me about once every 40 minutes. Fuck those assholes, they knew I was saving my life.
