What's the longest road trip in the world? To answer the question, we discount driving in circles, and limit the trip to continuous roadways, i.e. roads that are not interrupted by bodies of water. The YouTube channel Half as Interesting looks into the geography of the world's longest direct road trip, by looking at where the roads are.
While not using the exact same direct route, two Russian rally racers, Andrei Leontiev and Anna Zavershinskaya, drove from Cape San Vicente, Portugal, to Magadan, Russia, in 2014 in a Subaru Outback. They set a world record for the 16,000-kilometer trip, finishing in just over seven days (it was expected to take 15 days). You can see their video here. It's twenty minutes long and in Russian, but if you turn the auto-translate on, you may be able to follow it.
