I think this is a great way to teach young children about the world in a way that resonates with them. So much of their observation of the outside world occurs from the seat of a car (for better or for worse). It's a big part of their universe; they often pay such close attention to every little detail, so the differences around the world should be immediately obvious to them.
I love finding ways to talk about the world with my son, when i travel for work i get a small souvenir just so i have a physical object we can talk about from the place i’ve just been. Regarding your comment and after watching the London video it reminded me of our first trip as a family to London. We took electric black taxis all around the different sites in central London. I hadn’t planned on doing that but we had a tough stretch on the central line so the taxi was a welcome upgrade. Anyway my son loved the taxi, it is silent, has huge windows, glass roof and you really get to see London from inside. We did day time trips and ones at night. It was so good i tried to game taxi ranks to keep getting them. I think its good for children to have a worldview which is easy with youtube today.
