First off, welcome Billy.
In your first post you have hit the nail on the head as to why the cameras don't work. Where it's safe to speed they put up cameras, where it's dangerous to speed, so most motorists don't, there's no point in putting up cameras because they won't catch enough people to make the camera placement cost effective

It's a fundamental flaw, and the more people who refuse to be taken in by it, the better.
Don't forget that, quite often, these dangerous drivers are also unlicenced, uninsured and driving unregistered vehicles, so they are immune to cameras anyway.
Hope you enjoy your time on the forum.
