Talk about some global issues. After last week's protests in Paris led to the indictment of two Uber executives in France, the ride-sharing company has already hit another roadblock — on the other side of the world. In Brasilia, Brazil's capital, the city council voted to ban ride-sharing apps. And now Sao Paolo, the country's biggest city, is on its way to doing the same, voting 48-1 on Tuesday to prohibit its 12 million citizens from using smartphone-based ride-sharing apps.
