Cameras save 100 lives a year

I know you can argue about statistics till your blue in the face, but its good to see speed cameras get positive press coverage for a change.
To say its not speed that kills but dangerous drivers misses the point. If you are driving fast you are a dangerous driver. The faster you go the worse the carnage if or when you do crash.
I've never understood why they allow the manufacture of cars capable of speeds over 70 when the speed limit is 70.
When are people going to realise that driving isnt a freedom, its a privelege and one that they frequently exercise at other peoples expense.
