We, in the Northern Territory of Australia did stage a cannonball run a long time ago. During which a couple of people in a Ferrari went through a check-point (literally) which resulted in two deaths. So the powers that be said no more. At the time there was no speed limit on most of the (North South) Stuart highway in the Territory. Then the limits were to reduced to 110 km/h on the open stretches. Years later they were increased to 130km/h. A trial starts in a couple of months on a 200km section of the Stuart Highway between Alice Springs and Barrow Creek. This section will revert back to an open speed limit. Of course you would need to drive according to road conditions and other road users like road trains, grey nomads, wallaby's, Murdoch lookalikes etc.

Give or take it's about 3000km from Adelaide to Darwin, with Alice Springs being about in the middle of Australia.
