So, I have figured out precisely where the Grand Tour special started in Namibia. The first picture is from google maps, the 2nd is from the Grand Tour special, and the 3rd is the town of Rooibank, where they found their first road.
As you can see, that is exactly where they were.
That’s a bit familiar, isn’t it?
That’s where they got stuck! Along with the film crew!
Tire tracks from their cars!
