The document discusses the idea of creating a new type of shared transportation network that connects people with similar transportation needs and routes. It aims to address issues with public transportation being unreliable and taxis being too expensive. The proposed system would allow users to enter their transportation itinerary and be matched with others going in the same direction so they can share rides and costs through an approach modeled on the sharing economy. The goal is to launch in Brazil and sign up 25,000 users to generate $7 million in shared rides.
