I last drove through the NT outback 10 years ago. At that time it was the only place in Australia with no speed limit outside residential areas. The roads are generally straight and flat so you can see another vehicle coming from miles away. Roos and other animals can appear suddenly, but the trucks just plough through them. General rule was: don't drive after sunset unless you have good roo bars, otherwise drive behind a truck. So not much happens despite that, but at such high speeds it can just take a small woops (like a microsleep, or, in my case, realising there is a huntsman in the car) at the wrong moment for something like this to happen. And even though we have Flying Doctors it can take quite a while before you get help at the scene.

Yeah.. ? So that just means a lot of barbecues happen really fast. :D
