Speed cameras aren't saving lives

I have long argued that the safety claims of speed cameras are exaggerated and if people really care about saving lives, they should put more emphasis on driver education and on getting police highway patrols back on our roads. Now recent research by Liverpool University has found that speed cameras only save about 50 lives a year, not the 100 that was previously claimed.

Predictably, road safety charities have ignored the findings. If only we drove more slowly they reason, there would be no deaths. Come to think of it, why don't we bring back the red flag act?!
