The changes have been endorsed by transport researchers and street safety advocates as effective measures to help reduce the number of Kiwis killed and injured on the roads.
That's all there is to it.
I also initially thought that was the case, but it’s not! http://warp.povusers.org/grrr/collisionmath.html There’s no difference between 80km/h against a pole or wall vs 80km/h head on.
Fascinating! TYVM for that.
Though, I’ll argue that even in my flawed examples having double the number of vehicles in the collision is still worse: double the casualties. It’s just technically the same as two vehicles having independent collisions.
Oh, also: it improves the effectiveness of lowering the speed limit versus infrastructure upgrades.
Neat.
