This must be handled by the city or county level as where I live in California there's usually (always?) a little "4 way" sign under the stop sign when it's 4 way. Either way, this should be made consistent across the state and all of them definitely should have it added if they don't.

I wonder if I could get them to pay me a meaningful amount to identify all the intersections that need such a label. Like say, a bounty of $X for each non-compliant intersection or whatever. I think I could automate it with some simple perception neural nets. Or does the government just not give a damn about this kind of stuff ...

  Please report them in the SF311 app or at https://sf311.org/ https://sf311.org/. They won't pay you any money, but they're very responsive in my experience. Things usually get fixed.

    I'm happy to report the few I found to them. To whoever downvoted me: I wasn't suggesting that I would not report the ones I already know without pay, but rather that if I was funded, I would be able to carve out time to write code to find non-compliant intersections on a mass scale.

  Here in Australia sign upgrades or road modifications or both tend to occur either pre-emptively for no apparent reason in an effort to make traffic flow worse, or only after multiple people have died and the local community has been complaining for a decade.

Usually there's a yellow sign underneath the stop sign saying "Cross traffic does not stop". I don't know if it's a requirement, but it is common.

  In my experience that sign is usually only used for higher speed roads

  Not usual, IME they’re rare. I called SF 311 and requested such a sign at an intersection where people often seemed to be confused (10th and Moraga in the Sunset, IIRC). To SF’s credit, they reviewed the accident history at the location, and a traffic engineer called me back to explain that 1) they did not see a history of accidents there and 2) they don’t like to use too many of those signs, because they don’t want people to assume that the intersection is an ‘all way stop’ if the sign is not present.

    Maybe it's a sort of accident marker then.
