Uber app's 'radical redesign' gets more personal for you

"It's not just a normal update," Uber CEO Travis Kalanick said during a press briefing Tuesday at the company's swanky San Francisco headquarters. "This is a radical redesign and rebuild of the app from scratch." Uber's premise is simple: It pairs drivers with passengers via smartphone app. In the past seven years, it has gone from a small startup to one of the largest ride-hailing services on the planet, operating in more than 70 countries. With a valuation of $68 billion, Uber is also the world's highest-valued venture-backed company.
