They don't run the self-driving cars in the fog. Also, the streets aren't that narrow compared to most other major cities. It's certainly a step up from Arizona, though.
They absolutely do run in the fog, I live in a particularly foggy part of the city and take them several times a week.
And SF absolutely does have lots of narrow streets. There are a lot of neighborhoods where the roads are only wide enough for one direction of traffic at a time due to parked cars. Either you or the oncoming car needs to pull to the side in front of a driveway to pass. Waymo handles these situations expertly.
Based on your other posts in here you seem to have some kind of axe to grind and are making stuff up. Go watch some Youtube videos.

That is not a narrow urban road, unless you have about 3 inches on either side of your car. Drive in Europe or NYC sometime.
I have no axes to grind, but I find the optimism of "[X technology] works in [Y very easy condition], so it's going to explode any time now" somewhat tiresome and naive. I have been hearing it about self-driving cars for >10 years now (since the DARPA challenges). Plenty of technologies never leave the garden of that easy condition.
I've driven in NYC plenty. I think if they can navigate situations that are this narrow they can probably handle narrow roads in NYC adequately: https://youtu.be/YtbhoLp96DE?t=423
People said for a long time that self driving cars would never handle the complexity of SF, the fog, the rain, the hills, the bikes, the narrow streets, the crowds of pedestrians. Now that they do, I take the opposite view of you. I think the only hurdles left are snow, economics, and regulation. They are high hurdles, but seem solvable.
