This again! They were making noises about it about 5 years ago, but it ended up going nowhere: I think the ruling they were proposing was that City Dwellers had no requirement for bullbars, so if you lived in a city, you couldnt have one. You were okay if you were in the country, though.
Mind you, there are times when you just have to shake your head. Picking my children up from school yesterday and there was a late model top of the range 200 Series Landcruiser that had obviously never gone off road in its life because it was immaculate, that had the sort of bullbar on it that Id probably put on a farm vehicle in the Great Sandy Desert. Seriously, it was made of havy duty checkerplate and almost entirely covered the front of the vehicle and weighed more than the car itself.
My comment to Pete was that they obviously did a lot of driving through wildlife parks and wanted to be sure they would be protected in case they ran into an elephant. Serious overkill!!! ::)
But, yes, I do agree with the fact that you do need one if you any sort of country highway driving, just on account of roos or cattle, although Ive seen a few cases of roos ending up in the drivers lap after passing over the bull bar and through the window, also! :o
