Says someone who has obviously never driven or lived in NZ. The little shits sit in the middle of the road. And these aren't long highways, they're windy little country roads (eg. state highway 1).
You are right, I've never been to NZ but the way of handling the issue implied by the comment didn't put it in a context of "if dangerous then keep on going" but "aiming" for them (i.e. "population control").
