the reason for their calm acceptance is manifold - the 'positive outlook' is a part of cariocas' cultural dna, a mechanism they developed to protect themselves against an onslaught of cultural, economic and political struggles.

proud of this positivity, they turn to it in times of difficulty - on the busy roads, cariocas are prone to appreciate the beautiful views that surround them, enjoy the rhythms issuing from their radios, sing along, or immerse themselves in a conversation with a friend.  

the various hopes and aims of the people of rio have historically been difficult and troubling to obtain, so cariocas have admirably developed a way of enjoying and cherishing the journey instead - nowhere is this more explicitly evidenced than on the crowded roads of the city, where the final destination does not preoccupy daily travelers, who immerse themselves instead in the joys and pleasures of the present moment.
