I've seen this a few times, but I keep forgetting to ask about it,
Basically, I have driven past police cars parked on the side of the road and the driver has had the hand held radar sticking out the window pointing backwards, meaning that he can't really see you, he's obviously using the mirrors on his car and just having a 'rough guess' at getting the radar ligned up on your car.
I've only ever seen it on open, virtually deserted roads (mainly between Mildura and Bendigo) and very late at night, so he's really on going on your headlights aswell.
What would be the legalities of that? I was always under the assumption that they had to line it up on your front registration plate?
Or have things changed?
