Things like what? Traffic violence and risky behavior if a raising problem and it seems we don't have a solution for it despite many attemps. My view is that most of it comes from a small group of drivers. It's not "everyone speeds and uses their phone sometimes" but "there are people who speed recklessly and are on their phone most of the time". If you share my view then you want the camera in areas with the most traffic as the goal is to fish out and eliminate those dangerous drivers not punish sensible drivers who make mistakes sometimes.

Putting it on a major "safe" motorway is perfect. As you will have a chance to check most cars there. Being and to go at the speed limit where it seems safe (from inside the car anyway) to go faster is also the most important psychological trait for safe driving. Catching people who aren't up for that will improve safety in other places as well.
