One reason Uber thrives is because the ride-sharing app saves travellers from the messy business of unravelling public transport in unfamiliar cities.
I can vouch for that because I have just thrown in the mass transit towel in Sao Paulo, Brazil. I am travelling from the magnificent Museum of Art of Sao Paulo (Masp) out to the international airport. Instead of finding a bus-metro-airport express-bus combo, I am currently in an Uber, being driven by the aptly named Paulo. Right now we are in an almighty traffic jam in the John-Paul II Tunnel. Paulo has just warned me to close the window in case someone reaches in to nick the laptop on which I am writing.
