People who don't know the right-hand rule at uncontrolled intersections. The red vehicle in each picture has the right of way.
In fact we and Victoria are pretty much the only places in the world that drive this way.
It's counter to natural instinct.
As far as know Victoria doesn't have the give way to traffic turning right, Melbourne does however have the 'hook turn', - because the trams travel in the centre of the street, there is no room to queue to turn right, therefore right turning traffic has to pull into the left of the junction, then travels into the right hand street once the cross traffic gets a green light
