Uber Technologies, Inc. develops, markets and operates the Uber app. The app allows consumers to request an Uber driver to pick them up and drop them off at the nearest location. Uber drivers use their own personal cars and are viewed by Uber as independent contractors. Uber views the app as a conduit between the transportation providers and passengers. A passenger brought action against Uber after the Uber driver stabbed the passenger following an alteration. The passenger alleged that Uber was liable for negligent hiring, training, and supervision. Should Uber be held liable for the actions of its driver? What must the passenger prove to win this case?
