We have recently become eight billion on Earth. A boundless myriad of human beings, each with their own baggage of uses, customs, habits. Each with their own language and culture, each ready to face existence in their own way, following different patterns, models and rationality. Yet there is one thing that unites us all, no one excluded, here on planet Earth. This thing is called a road. Yes, because each of us will use, sooner or later, a road. And it doesn't matter if we prefer to fly, sail or walk. If we have a car or a motorbike or just a bicycle. And it doesn't even matter if we learn to drive or never want to get a driving licence. Because every human being, in the course of their existence, will be destined to travel hundreds, perhaps thousands, if not millions, of kilometers on the roads. Despite this bond being so intimately inescapable, none of us - or almost none - really know what the roads are like today. Also because it is very difficult, if not impossible, to enter a construction site. And that is why we, instead, have done everything we can to enter, with our cameras. And, as always, we take you with us in this new episode of Mezzi Speciali, where we tell you all the secrets of a process that is still little known, but absolutely spectacular.
