First time visiting, i arrived in Sāo Paulo in a Bus, when i saw the sign "Welcome to Sāo Paulo i stood up and started to get my things... When we got to the São Paulo Bus Station, 5 hours later, i understood why the other passengers were very amused by my behavior.
I know so many people who choose to drive. It blows my mind. Like, yeah, the subways can be frustrating, but nowhere near as frustrating as driving in the city.
