Uber is taking its ride-hailing app down a new road in an effort to make it smarter, simpler and more fun to use. The redesigned app also will seek to mine personal information stored on smartphones in a change that could raise privacy concerns, even though it will be up to individual users to let Uber peer into their calendars and address books.(AP Photo/Eric Risberg, File)
