04fuxake: The Dutch got their safe roads because they were sick of kids being killed by cars. Kiwis just buy bigger and bigger cars and then run them over in our driveways.
This is simplistic.
The Dutch have safe roads because they don't drive on them much. They don't drive much because they have an effective public transport system. They have that mainly because they live in dense housing, so that there are many more people/km, which makes good public transport economically viable, and easier and cheaper than driving a car.
