The last year has been rough for ridesharing app Uber, what with a litany of regulatory challenges, lawsuits over intellectual property infringement, and questions about gender relations in the workplace. The new year even brought a Twitter-driven #DeleteUber campaign. So, how’s the business of ridesharing doing? Well, we don’t have good government statistics for 2016 yet, but we do now have such data for 2015, and these show that the hyper-growth of ridesharing that we documented last year is, if anything, accelerating.
