At this point in time, I believe they cannot issue a moving violation to an autonomous car as it does not have a driver. The safety driver (if there is one), can be cited though.
I assume that traffic violations like this are handled differently than those with a human driver given the permitting and reporting required for the self driving companies operating in SF. That said it’s SF so who knows…
AFAIK: no. Most PD are very against use of photo-based retroactive citations, and that's what this would require. Of course in theory they have the authority to do so, it just never seems to happen.
