So you could use this technology to track and predict police movements too eh? Hmmmmmmmmm
Technology like this poses a unique challenge because it's impossible to actually stop people from doing it if they want to. It's just a camera pointing outside and software in the end. Obviously more regulations (with real consequences) need to be enforced because of how easily it can be abused by police but that's what we do (or should do?) for all powers we give them.

How do we stop police from doing what anybody with a little tech experience can do? Even if we did legislate it out but then someone is publicly doing it with no explicit purpose, are the police allowed to use it too? How could you ever stop them?
At the opposite end of the spectrum I often think about modern safer ways of policing and one of those ways is to limit police interactions when possible. Why should I get pulled over for a speeding ticket or busted headlight? Take the data, have it verified by actual legal scholars (rather than empowered thugs) and send me the ticket in the mail. Why should the cop in the car ever be notified this is happening?
Like always, technology poses new risks and benefits that should be explored.
I'm trying to think of some use cases, I can really only think of two that it might be used for. Space travel and doomsday vaults.
Space travel is a no brainer and these could be used as another form of storage that contains legit everything humanity knows while having the critical stuff run on standard reliable hardware. Incredibly small and lightweight storage in comparison.
Doomsday vaults would be the same idea. Having these as another way of storing information that otherwise we would never keep due to the immense size.
