While Europe dominates with structured high-speed limits and legendary roads like the Autobahn, other parts of the world also boast roads that push the boundaries of legal velocity. Stretching across the heart of the Australian Outback, sections of the Stuart Highway in the Northern Territory were once famously limitless—and although a 130 km/h (81 mph) cap has been reinstated in most areas, the road remains one of the fastest legal highways in the Southern Hemisphere. It's straight, open stretches invite long-distance driving with minimal traffic.
