For riders, there's the Waymo One privacy policy: https://support.google.com/waymo/answer/9184840?sjid=5254444...
Beyond that, https://support.google.com/waymo/answer/9190819?hl=en seems to be more relevant to your interests.
Your second link does mention cameras and microphones outside the car but doesn't mention what they keep (full video? stills? LIDAR? RADAR?) or for how long:
“Waymo’s cameras also see the world in context, as a human would, but with a 360° field of view. Our high-resolution vision system can help us detect important things in the world around us like traffic lights and construction zones. Our systems are not designed to use this data to identify individual people.”
The “Our view on your privacy” section links to the same page as your first link, and that page's “What we keep” section is explicitly only about riders:
“We will retain information we associate with your Waymo account, such as name, email and trip history, while your account remains active.”
Flock is the same way. For example here's the Flock privacy policy from one of SF's fine local shopping centers: https://www.stonestowngalleria.com/en/visit/lpr-privacy-poli...
> Video Clips captured by the LPR system will automatically be deleted after 30 days; although Images are deleted when no longer needed, the data obtained from the Images may be retained indefinitely. Should any information from the LPR Dashboard be needed to assist with a security or law enforcement matter, it may be retained indefinitely, in paper and electronic form, as part of the security file until it is determined it is no longer needed; in addition, it may be shared with local law enforcement who may retain it in accordance with their own retention policy.
If anyone can share a link to a similar IRL privacy policy for Waymo I would love to read it. The one on their website is conspicuously labeled Waymo Web Privacy Policy lol
