According to a separate report from the Information, a former Uber manager raised concerns about the driverless cars' road readiness in an email sent days before the accident In a voluntary safety assessment filed with the National Highway Traffic Safety Administration, Uber said that with a separate systems engineering testing team, it's better positioned "to reason over many possible outcomes to ultimately come to a safe response" and will in the coming months form a self-driving safety advisory board of outside experts. "At Uber, we believe that technology has the power to make transportation more efficient, accessible, and safer than ever before," Meyhofer wrote."Self-driving technology has the potential to make these benefits an everyday reality for our customers, but it's not going to happen overnight. Building best-in-class self-driving technology will take time, and safety is our priority every step of the way."
