My impression was that the series suggests motorcycles are as cool as smoking.
My impression, after actually watching both seasons multiple times, is that the series suggests it's cool to travel outside your own country and continent, meet strangers, learn about their culture, partake in their customs, cook and eat their food with them, and perhaps on the side bring attention to socioeconomic issues through a partnership with UNICEF. And that doing all these things on two wheels instead of four can help connect you to the land and the people, and aside from crossing a roadless chunk of Mongolia, it might even be more fun.
That's just me, though. Maybe I wasn't watching it correctly.
