Well there are many issues surrounding Speed Cameras as the website analyses.
Road safety is a highly involved and sophisticiated human behaviour that takes good intelligent research, excellent advice and development to help improve the road state conditions.
Key factors in driving are :
skill
knowledge
experience
psychology
beyond that :
concentration / consideration / courtesy
observation - everything possible
anticipation / awareness / attitude - and risk assess each hazard
Space - speed reduction & 2 sec rule - from you and others all about you - control your space
Time - to react to potential hazard and the earliest anticipation of hazard

Ten seconds to impact - as avoiding crashes is what Good Road Safety is predominantely all about, Speed Cameras do nothing to achieve this aim and in fact cause more problems through negative effects than they ever solve.
By all means call me ... to discuss further.
