Thought this might be of interest....
I am trying to take a balanced approach to this looking at all points of view, but my experiences with uber have been fantastic and I am disappointed that rather than working on a comprehensive solution that would benefit everyone, the local governments just bent over and took it from the taxi folks.
In cities as big as Sao Paulo and Rio I cant beleive that taxi's and uber each wouldnt find enough business.
