Why do you think it is now an issue? Flock is a private company where other traffic cameras I'm familiar with were not. Those were problematic and in my state they were deemed not legal and removed. The other type of cameras I'm not a fan of are the ones for the toll roads. They take shots of license plates even if you have a tag. I don't know if they are searchable by law enforcement, but I have no reason to think they are not.

Any camera system that can be used to track people even if that's not the sole purpose is problematic, but when the entire purpose of the camera is tracking people then it is especially egregious. It's not a problem now, but they've turned the knob to an 11.
