Bluester, 100% with you buddy.
I don't necessarily have a problem with having speed cameras, I do have a massive problem with the misguided belief that they are there to make roads safer, I have a massive problem with the fact that we are told they make roads safer when the road toll indicates to the contrary, and I have a massive problem with the fact that governments are neglecting effective road safety campaigns to take the easy and economical option of just installing speed cameras.
Speed in and of itself DOES NOT cause crashes, if that were the case, then every racing car driver on the planet would be dead, as would anyone who drives on the Autobahn. Speed combined with other factors such as tiredness, talking on the phone, weaving in lanes, not paying attention to the road ahead, etc does cause crashes - however how often do you see patrol cars driving around on highways booking people for inattentiveness or inconsiderate driving maneouvres? Rarely. If they were genuinely serious about it, that's what they would be doing. When you're in a bunch of traffic on the motorway and there is a police vehicle in the mix, everyone drives safer and sticks to the speed limit.
Focusing so much on "speed kills" just makes people so shit scared of being booked for speeding that all they care about is that they're doing the speed limit, and they completely disregard all other road safety factors such as scanning the road ahead, staying in the left lane, paying attention to what's going on around you etc.
