We all hate speed cameras,don’t we?They’re not there to slow drivers down and lower the road accidents;they just make money for the government.They trick us,cost us cold hard cash,disturb us from driving properly and are unfair.

Well,here’s a surprising thing:what if there were facts that the boring cameras actually saved lives?It’s a conclusion difficult to ignore when you look at what’s happening in France,a country with a historically poor record of road safety.

There were 16,617 road deaths in 1972 in France for example,but that dropped to 8412 by 1995 following rules such as compulsory(强迫的)seat belt wearing in 1990 and a lowering of the blood alcohol limit to 0.05 in 1995.

Last year, the road deaths dropped below 5,000 for the first time,or 4.9 percent less than2004.Comparing road deaths to populating in 2005,that’s about 817 per million people compared with Australia’s 806.

And guess what?Last year the number of speed cameras on French roads reached 1,000 and the government plans to double that within the next three years.

Okey, you know the arguments on the increased traffic safety and cameras. for-inco me, but in seems in France there’s been a major cultural change brought on by radars and other laws. A theer-hour, wine-soaked lunch with a quick rush back to the office is no longer on.

Traveling on the highways,it is rare to see anyone breaking the 130km/h speed limit when one few traveled below it. The speed cameras are clearly signed so drivers know when they are coming There’s even all official web site listing fixed and mobile camera locations and it is updated regularly

Maybe it is because of such transparency by government,rather than the secrecy too often used by authorities in many other countries that more French can enjoy their life thanks to speed cameras
