I don't think that complicates anything from a policy perspective. If self-driving cars are good (i.e. safer than human drivers), we should be rolling them out. If a small number of people interfere with them or damage them, we should just arrest those people and prosecute them for the relevant crimes. I don't think that vandalism of self-driving cars is going to be a serious issue long term, given that anyone vandalizing them is going to be on camera, plus people will just get used to them and find other things to be mad about.
SFPD won't do anything about property crimes, to include vandalism, other than to take a preliminary report, on a schedule determined by the department (eg: you call them, they show up 8-12 hours later, uninterested in taking your report). This is because, currently, their DA's office isn't going to prosecute any property crimes.
That can all change, but speculating about the nature or timing of any changes like that is well outside my area, so I'll sit and watch from a distance.
And, again, I'm not vested in any outcome here. It'll work out however it works out, and I'm 2000+ miles away from it, so it won't have much effect on my life.
