Ok what makes drivers unsafe and unaccountable?

I live in a place with a lot of traffic violence, and there’s negligible enforcement. I’m looking for a practical way to keep drivers accountable and reduce the violence.

I think cameras on the intersections have to be part of that strategy. I’m inclined to believe a responsible implementation is possible, and I’d like to see more discussion of what that could look like.

Are there any implementations of camera based traffic safety networks that are actually kind of good, in terms of privacy, responsible data handling, and effectiveness?
