I have even had the Cops flash their headlights at me....
Shortly followed by the roof lights, and a wagging finger
Yes. I even gave an oncoming ute a "thumbs up" when I got a flash from it. Five minutes later I was being handed a piece of yellow paper by its country cop driver with some BS about 18 kays over the limit or somesuch. Felt very hard done by, having seconds before driven conscientiously through a long deserted main street at 50 kph.
