Self-Driving Uber That Hit Pedestrian Wasn't Set to Stop in an Emergency

The crash marked the first pedestrian death involving a self-driving car and ignited a broader discussion about whether the driverless technology that auto and tech companies are racing to develop is ready for the real world. It also illustrates the challenges Uber has faced in developing software that can detect hazards on the road and respond appropriately, as the ride-hailing company chases rivals such as Alphabet Inc.'s Waymo and General Motors Co.'s Cruise Automation, which aim to deploy robot taxis that could pose as a threat to Uber's business. Uber was testing a fleet of Volvo Cars sport-utility vehicles that come equipped with automatic emergency braking and other safety features. The vehicles, however, were modified by the ride-hailing company, which equipped them with cameras, sensors and onboard computers. An operator rides in each vehicle, prepared to take the wheel to ensure safety as needed.
