My nephew had a pretty spectacular accident in Adelaide about ten years back, where he was waiting in a narrow two lane (one lane going each way) road to turn into his house..a car was approaching from the other way. There was a line of cars parked beside him on the side of the road, and he was about to turn across when a car flew through on his left, trying to squeeze through the small gap between my nephews car and the parked cars, and in doing so he sideswiped the parked cars pretty heavily, and bouncing back and smashing into his car, tearing off the front left hand wheel and mudguard. It goes without saying that the other car was absolutely flying...
When it went to court, my nephew was assuming he would get the full payout for his written-off Subaru, but at the end of it all, it was assessed to be "80% the other drivers fault, 20% your fault". My nephew hit the roof, and the apparent reasoning was that even if you are completely innocent, you won't get much better than an 80-20 ruling. Just by being out on the road, you are taking a "risk", they say, and this means that you are always "at fault" in some small percentage just by driving on a public road, no matter what.
This kind of ruling may have changed, but I have since heard of similar things happening here in Queensland.
One case in point: about five years ago, my wife was driving along in our old Fairmont, and slowed and indicated to turn right into a side street. Close behind her was a guy on a Harley Sportster, ahd he completely failed to notice the indicators and brake lights on our car, and as my wife began her turn, he decided she was going too slow and tried to overtake! He glanced off the front guard of our car, and by some miracle stayed upright. He had a massive bruise on his thigh, and the Harley had a dented tank, broken indicator, and scraped motor. The Fairmont had a big ding in the guard and a scrape on the side of the front chrome bumper. He had full comprehensive insurance, and his insurance covered our damages, but our full comprehensive insurance also had to cover a portion of the damages to his bike! He was completely, 100% at fault in anyone's eyes, but apparently not in the insurance companies eyes...
