Waymo’s
Autonomous Cars Cut Out Human Drivers in Road Tests

The
self-driving car is edging closer to becoming driverless. Waymo, the autonomous
car company from Google’s parent company Alphabet, has started testing a fleet
of self-driving vehicles without any backup drivers on public roads, its chief
executive said Tuesday. The tests, which will include passengers within the next
few months, mark an important milestone that brings autonomous vehicle
technology closer to operating without any human intervention.
Dozens
of companies are testing self-driving technology on public roads across the
United States and some autonomous features are available in today’s cars. But
Waymo is believed to be the first company to test vehicles on public roads
without a driver ready to take over in an emergency. “Our ultimate goal is to
bring our fully self-driving technology to more cities in the U.S. and around
the world,”
John
Krafcik, Waymo’s chief, said in prepared remarks at a technology conference in
Portugal on Tuesday. “Fully self-driving cars are here.” The tests are a show
of engineering prowess by Waymo at a time when traditional automakers and other
tech companies like Uber race to develop similar vehicles. Waymo is limiting
the trials to a region around Phoenix, where it has been conducting a
ride-testing program this year, and plans to expand the testing area over time.
The
company said it planned to use the driverless vehicles to launch a commercial
ride-hailing service for the general public, but did not offer any detail on
when, where or how. Waymo said its driverless cars hit the public roads last
month. The company did not say whether it was testing the driverless cars in
environments considered challenging for autonomous vehicles, like bridges or
tunnels, or more difficult conditions, like driving at night or in rain and
snow — usually not a big concern in the dry Phoenix climate.
While
the prospect of cars without emergency drivers may raise concerns among some
passengers, Waymo said it had confidence in the safety of its self-driving
technology. It has included backup systems like a secondary computer to take
over if the main computer fails. And though the cars are driverless, they are
not entirely without humans, at least for now.
Waymo
employees sit in the back seat of the cars, monitoring them, a company
spokesman, Johnny Luu, said. Once passengers join the tests, they will be able
to contact Waymo support staff with a button inside the car. If the cars are
involved in a crash, they are programmed to respond appropriately, including
pulling off the road on their own.
Driverless
cars are regulated by a patchwork of state laws. Arizona, like many states, has
no restrictions against operating an autonomous vehicle without a person in the
driver’s seat. On the other hand, California, where Waymo is headquartered,
requires any self-driving car to have a safety driver sitting in the front. In
December, Waymo published a report for California’s Department of Motor
Vehicles about how frequently its car “disengaged” —
deactivating its autonomous mode because of a system failure or safety risk and
forcing a human driver to take over. In the report, Waymo said this happened
once every 5,000 miles the cars drove in 2016, compared with once every 1,250
miles in 2015.
Consumer
Watchdog, a frequent critic of Alphabet, said that data demonstrated that the
cars are not ready to drive without any human intervention and that Waymo was
following the Silicon Valley model of “beta testing” a new technology on the
public. “It’s the wrong approach when you’re dealing with self-driving cars,”
said John M. Simpson, a director at Consumer Watchdog.
“When
things go wrong with a robot car, you kill people.” Researchers believe
self-driving cars can be safer than cars operated by human drivers because they
are programmed to adhere strictly to traffic laws, they don’t get distracted,
and they usually refrain from taking unnecessary risks. Timothy Tait, a
spokesman for the Arizona Department of Transportation, said the state was on
pace to exceed 1,000 automobile-related fatalities this year and that its top
priority is the public’s safety — particularly by advancing efforts to reduce
crashes and deaths on its roads. “We are closely monitoring emerging
technologies like self-driving cars that may ultimately support safer travel
and open up opportunities for populations who today are unable to drive for
themselves,” he said in a statement.
Waymo,
which started as a research and development project for Google in 2009,
maintains what many in the industry consider a technological advantage over its
competitors. Waymo said its autonomous vehicles had driven more than 3.4
million miles on actual roads — with safety drivers — as well as running 10
million miles every day in a virtual simulator. In his remarks, Mr. Krafcik
said Waymo sees a ride-hailing taxi service as the first commercial application
of the company’s driverless car technology, though there could be other uses in
logistics and public transportation.
Taking
the human out of the equation will fundamentally change transportation and
change how people buy cars, said Mr. Krafcik, who was an executive at Hyundai
Motors before joining Google. “Because you’re accessing vehicles rather than
owning, in the future, you could choose from an entire fleet of vehicle options
that are tailored to each trip you want to make,” he said. “They can be
designed for specific purposes or tasks.”
