Effectiveness of speed cameras in preventing road traffic collisions and related casualties: systematic review

Peter, you wrote:

"Or are they going to persist in saying things like: "everyone speeds, and I thank god that they do." For a so-called 'road safety campaigner,' is that not one of the most ridiculous, fatuous and incredibly irresponsible things to say? That is a pretty pathetic argument to try and convince people that fast traffic is safer than slow traffic and that speed cameras *increase* road deaths. How can you argue sensibly with such people?"
