“It's a pretty glaring indication that we're not there yet，” says Matthew Johnson- Roberson, co-director of the University of Michigan's Ford Center for Autonomous Vehicles, who's working with automakers to develop robot rides.Waymo, owned by Google parent Alphabet Inc.and recently valued at $250 billion by Jefferies Research LLC, declined to comment.In a blog post, Chief Executive Officer John Krafcik said the human safety drivers were at work in Arizona to make riders feel more comfortable.
Waymo's timid rollout is the latest speed bump for a technology touted as certain to save the world from road deaths.As auto and tech giants converge on Las Vegas for the consumer electronics show known as CES，which formally kicks off on Jan.8 and includes a keynote from Krafcik, the seemingly boundless optimism that surrounded driverless cars only a few years ago has been tempered by a slew of persistent technological challenges and big questions about near-term business models, especially as a recession looms.4tMost of the automakers are chasing a business model that has yet to be proven that elusive robo-taxi.” says Craig Giffi, head of consulting firm Deloitte's U.S.automotive and industrial products practice.
At CES, driverless and auto technology will cover 300,000 square feet of floor space, more than the total size of many stand-alone car shows，and the auto industry is continuing to pour billions into self-driving cars.Ford Motor Co.CEO Jim Hackett said in November that the market for autonomous vehicles and other mobility services could reach $10 trillion half the size of U.S.gross domestic product.Annual sales of self-drivers will hit 33 million by 2040 and account for more than a quarter of global vehicle deliveries, according to researcher IHS Markit.
That's why automakers and tech companies are rushing to get robots on the road.General Motors Co.'s Cruise Automation plans to debut its automated ride-hailing business in a U.S.city in 2019, and Ford promises to deploy tens of thousands of self-drivers on the streets of multiple U.S.cities in 2021 as part of a profitable business moving people and packages.Even Uber resumed testing its autonomous Volvos in December, only nine months after one struck and killed a pedestrian in Tempe, Ariz.
But a study from Deloitte suggests things will move more slowly than expected.Half of the 25,000 consumers Deloitte surveyed globally said they didn't believe autonomous vehicles would be safe, up slightly from 47 percent a year ago.Just 39 percent of them trust automakers to bring the technology to market.Most surprising: Only 12 percent of U.S.consumers reported using services such as Uber and Lyft once a week, half the rate of a year ago.Taken together, the findings undermine the near-term business case for the robo-taxi,which relies on an ever-growing pool of consumers ditching their cars.
As long as human safety drivers are required, profits are out the window.“The economics of that don't work out at all，” says Johnson-Roberson，the University of Michigan technologist.He says the only way to remove safety drivers is to isolate autonomous cars in their own lanes, walled off from unpredictable humans.Among other things, driverless cars still struggle to merge into traffic.
