Waymo ditched autopilot feature after test user napped behind wheel

ATWATER, Calif. -- Alphabet Inc.'s self-driving car unit stopped developing features that required drivers to take control in dangerous situations, its CEO said Monday, as autopilot reliance left users prone to distractions and ill-prepared to maneuver.The decision followed experiments of the technology in Silicon Valley that showed test users napping, putting on makeup and fiddling with their phones as the vehicles traveled up to 56 mph.John Krafcik, the head of Waymo, which was formed in 2009 as a project within Alphabet's Google unit, told reporters that about five years ago the company envisioned technology that could autonomously drive cars on highways as a quick way to get on the market.Other self-driving automakers include similar autopilot features for highway-driving in vehicles, but they require drivers to take over the steering wheel in tricky situations. Waymo planned to do the same."What we found was pretty scary," Krafcik said during a media tour of a Waymo testing facility. "It's hard to take over because they have lost contextual awareness."Krafcik said the company determined a system that asked drivers to jump in at the sound of an alert was unsafe after seeing videos from inside self-driving cars during tests.The filmed tests were conducted in 2013, with Google employees behind the wheel. The videos had not been publicly shown until Monday's event, Waymo spokeswoman Lauren Barriere said.The company decided to focus solely on technology that didn't require human intervention a couple of days after the napping incident, said Krafcik, who joined as CEO in 2015. It has also since argued against allowing "handoffs" between automated driving systems and people."Our technology takes care of all of the driving, allowing passengers to stay passengers," the company said in a report this month.
