Uber ramps up safety efforts after criticism

Uber said Wednesday it was ramping up safety in response to rape allegations against a driver in India and growing concerns about background checks for operators of the popular ride-sharing service. Phil Cardenas, safety chief for California-based Uber, said the company was implementing a new global "code of conduct" and creating worldwide "incident response teams" to reassure riders who have become increasingly worried for their safety after several high-profile incidents. &
