Other than the video camera that's presumably recording everything around them and the real-time location reporting? If you just want to damage it you can chuck a brick at it from its blind spot, but that's true of everything.

I wondered the same. I was actually shocked to see one on the street with it's camera still attached, moving unmolested past a bunch of people.

Knowing Berkeley this seems like a pretty awful idea. People are going to steal these things immediately.

I wouldn't be surprised if communists and Antifa would destroy them on purpose in the name of fighting for "working class" and jobs. And if not them, then other thieves/vandals do the job.
