I wonder how many accidents and fatalities are due to poor layouts (that are hard to fix), inadequate signage, and unique designs that are "safer," but add enough mental overhead that you're paying more attention to where you should be so you're not in a bus-only lane rather than looking out for pedestrians. Driving in SF can be complicated when you're not familiar with the streets. Intersections feel like multiple clever solutions stacked together.
