The article isn't specific enough to know for sure whether that's average profit per ride, or whether that's the margin they skim off the top per ride Does that $0.19 come from (total margins from US rides - total US operating expenses) / (total number of US rides), or is it (total user payment - total driver costs) / (total number of US rides). The former means that they're actually bringing in about 10m in total net profit per month, which isn't terrible. The latter means they're probably not doing so well.
