Was on a similar bit of straight road out past Longreach - had remarked to a guy in a servo that it would be a good spot for a quick run cos cops couldn't hide anywhere - he said don't kid yourself - there are small undulations in the area and the cops plant "hull-down" in the middle of nowhere and get a wonderful shot of you coming from miles away, without even having to interrupt their snacking.....
Then they just yawn, have a stretch, hop out of the car, and hold their hand up........
