In the UK, speed cameras are painted bright yellow.

These are Raybans - designed for social dynamics - with the addition of a concealed camera.

Both are “any camera” that can dig out realtime information about people. Not this comment per se, but the lack of critical thinking in comments here on topics like this is frightening. Especially given this is where you’d hope to find the discussion, and likely contains many people steering this technology and change. And to be honest, my critical thinking ain’t that sharp but I can see something interesting beyond its any camera.
