Government statistics aside, They don't give the breakdown for the road types involved, the type of collisions or what they define as 'excessive speed'. One definite statistic is the fact that German's Autbahns (no speed limits) are a damn site safer then our motorways, though some of that can be put down to the fact they are well maintained and have more money spent on them(one more failure of our government, and a proof that money isn't being spent as wisely as it should?). I wonder how many of those statistics involve pedestrians, running red lights or just driving like a clown (drinking etc) as well.
Until they show some definite predictions, and some trials where average speed cameras have improved the CO2, improved safety and improved journey times it is still one stealth tax if you ask me.
