True; I should have said metadata and not just data since you're right that the volume of raw images would be too big to store indefinitely. It's way more feasible to process the raw images and store the inferences, like number of persons visible in last 5 seconds, or dates and times a person who looks like me has been seen by a Waymo while my particular Android phone is nearby, or dates and times they have seen [my OCRed car number plate].

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
