NSW has a problem with people throwing stones which does not exist in other state. What is wrong with these people? The problem is so great that the state government thinks that it is necessary to put up fences over the freeways. I am not sure how this helps as a stone thrower could just throw the stone over the fence. From what I remember, this hysteria was caused by a small number of children. Hundreds of pedestrians die each year on the roads, but they probably don’t matter.
What you will see in NSW:
The veiw from a bridge of the eastern freeway in Melbourne, clearly clear of fences.
Aparently people also will toss stones sideways onto the freeway, not to mention down onto the houses and factories…
