Trent Kalanick's quote summarizes Uber's original goal of providing on-demand transportation with the push of a button. However, Uber now faces strategic issues as both a business and sharing economy platform. As a business, Uber leverages its technology and labor cost advantages but also faces weaknesses from lawsuits and regulations. As a sharing economy platform, Uber benefits communities but avoids some taxes and responsibilities of traditional transportation providers. Rivals increasingly challenge Uber's model on various fronts.
