Agreed, but they will continue to place the cameras wherever they can catch the most people.
Motor Cycle News wrote to every "Safety Camera Partnership" in the country to find out how they justified the camera sites. Many were using accidents which were nowhere near the camera sites as evidence.
The best (worst!) was an accident on a cycle path .... so someone falling off a pushbike on a cycle path was used to justify a camera site on a nearby road!
In another case, all the accidents were at a junction, but the cameras were some distance away. So why not work out why the junction is a problem, and fix it? A cynic might think it's because redesigning a junction COSTS money, but a camera MAKES money ....
