At the risk of sounding too skeptical but these are the kind of quotes dreamed up by the marketing department. The kind of quotes that have no connection to the actual mission of a company. There is probably no KPI anywhere to be found within Uber that says: "Traffic reduced %".
Even worse these quotes are often all based on "gut feeling" and "well sounds logical" kind of emotions with no factual basis whatsoever. Which probably isn't a surprise since it's marketings task to handle emotion.
