Living in Sao Paulo, I only take Uber when it's really hot and I don't feel like using the subway. Uber drivers are constantly at war with taxi drivers, to the point that if I know there's a taxi stand close to where I'm going to, I'll set the destination a little further away. I can't remember a single Uber driver telling me he started making more money when he started accepting cash. Most of them said they would never accept anything besides credit card, for safety.
