So I kinda get the frustration. But who looks at the lowest road toll we've had in over a decade, and what may even be the lowest per capita road toll ever, and thinks "this has got to stop"?
Yes, the article states:
Bishop insisted it was "safe to do these changes". "The number one factor driving deaths on our roads is drugs and alcohol."
But physics dictates that when these drug and alcohol drivers drive into a family car, cyclist, pedestrian, everyone is more likely to survive even with only small reductions in speed.
