An excellent site called Fast and Safe has been put together which brings some greatly needed facts to the road safety debate, rather than mere LTSA slogans.
They show how following LTSA advice, you would need 2 kms of clear space to pass a truck travelling at 90 km/hr.
The site has a lot of excellent data from NZ and overseas. You may disagree with their point of view, but they can back what they say with a lot of research.
Personally I welcome a debate on whether the current focus on arbitrary limits and rules actually saves more lives than educating people to drive to the conditions.
I also support making people resit their licensing tests every five to ten years as a far more effective road safety measure.
