I think you are dramatically underestimating the terrorism concern. From public news reports we know almost 400 Flock cameras have been destroyed in acts of widespread grassroots criminal vandalism, and I am sure Flock knows the much higher true number. Likewise for Waymo, we know of at least half a dozen vehicles destroyed and at least two dozen temporarily disabled, and I am similarly sure Waymo knows the much higher true number. From the point of view of a data center executive who has chatted to a Flock or Waymo executive at a social event in the last few years, the risk of vandalism/terrorism is neither hypothetical nor plausible, but literally real and already happening.
