It's incredible how humans have managed in only the last hundred years or so to build road systems that connect vast stretches of land. The largest such system is in Eurasia and Africa, which are already entirely drivable. This new video from RealLifeLore speculates on how we could go about connecting the rest of the world.
There are some major issues. One of them is the Bering Strait, the frozen sea between the tip of Russia and Alaska. Though it's possible to build a bridge there, the harsh weather conditions would make it extremely difficult and costly. Another problem is the Darién Gap, an area of swampland between Panama and Columbia full of paramilitary troops, drug lords and other unpleasant conditions that make building a road there near impossible. Also, the route described in this video would require building a bridge between the tip of Morocco and Spain, the inlet to the Mediterranean Sea. This isn't actually necessary, since there are bridges over the Suez Canal connecting Africa to Europe, but it would make the route longer and more all-encompassing.
But assuming we overcome these issues, the road we could build from the town of Punta Arenas, Chile, to Cape Town, South Africa, would be 32,000 miles long and take 28 days to drive. Not exactly the most efficient way to travel, but the sights would be amazing.
