This is probably old news to many of you, but it was a new one on me. I'm in Canberra at the moment and, on the way home on the bus this afternoon, I passed the aftermath of a traffic bingle. What really interested me was that one of the attending cop cars was a black Holden SS ute with its blue and reds concealed in its tail light clusters (couldn't see what it had at the front), which would have rendered them invisible if they hadn't been on. Sneaky. In WA the unmarked cars aren't too hard to spot if you've got your eyes open but the coppers over here seem to be a bit smarter about the camouflage.
