Self-driving
cars getting dinged in California Published May 11, 2015
Four
of the nearly 50 self-driving cars now rolling around California have gotten
into accidents since September, when the state began issuing permits for
companies to test them on public roads. Two accidents happened while the cars
were in control; in the other two, the person who still must be behind the
wheel was driving, a person familiar with the accident reports told The
Associated Press. Three involved Lexus SUVs that Google Inc. outfitted with
sensors and computing power in its aggressive effort to develop
"autonomous driving," a goal the tech giant shares with traditional
automakers. The parts supplier Delphi Automotive had the other accident with
one of its two test vehicles. Google and Delphi said their cars were not at
fault in any accidents, which the companies said were minor. Since September,
any accident must be reported to the state Department of Motor Vehicles. The
agency said there have been four, but would not comment about fault or anything
else, citing California law that collision reports are confidential. The person
familiar with the accident reports said the cars were in self-driving mode in
two of the four accidents, all of which involved speeds of less than 10 mph.
The person spoke on condition of anonymity because they were not authorized to
discuss the reports publicly. Five other companies have testing permits. In
response to questions from the AP, all said they had no accidents. In all, 48
cars are licensed to test on public roads. The fact that neither the companies
nor the state have revealed the accidents troubles some who say the public
should have information to monitor the rollout of technology that its own
developers acknowledge is imperfect. John Simpson, a longtime critic of Google
as privacy project director of the nonprofit Consumer Watchdog, pointed out
that the company's ultimate goal is a car without a steering wheel or pedals.
That would mean a person has no power to intervene if a car lost control,
making it "even more important that the details of any accidents be made
public - so people know what the heck's going on. A chief selling point for
self-driving cars is safety. Their cameras, radar and laser sensors give them a
far more detailed understanding of their surroundings than humans have. Their
reaction times also should be faster. Cars could be programmed to adjust if
they sense a crash coming - move a few feet, tighten the seat belts, honk the
horn or flash the lights in hope of alerting a distracted driver. A higher
priority so far is teaching them to avoid causing a serious accident that could
set public and political acceptance of the technology back years, said Raj
Rajkumar, a pioneer of the technology with Carnegie Mellon University. In the
October accident involving Delphi, the front of its 2014 Audi SQ5 was
moderately damaged when, as it waited to make a left turn, another car
broadsided it, according to an accident report the company shared with AP. The
car was not in self-driving mode, Delphi spokeswoman Kristen Kinley said.
Google, which has 23 Lexus SUVs, would not discuss its three accidents in
detail. The accidents are not Google's first: In a briefing with reporters a
year ago, the leader of Google's self-driving car program acknowledged three
others between when the company first sent cars onto public roads several years
ago - without the state's official permission - and May 2014. In a written
statement, Google said that since September, cars driving on streets near its
headquarters in Mountain View had "a handful of minor fender-benders, light
damage, no injuries, so far caused by human error and inattention. Google said
that while safety is paramount some accidents can be expected, given that its
cars have gone "the equivalent of over 15 years of typical human
driving," or approximately 140,000 miles. The national rate for reported
"property-damage-only crashes" is about 0.3 per 100,000 miles driven,
according to data from the National Highway Traffic Safety Administration. In
that context, Google's three in about 140,000 miles may seem high. As the company
pointed out, however, perhaps 5 million minor accidents are not reported to
authorities each year, so it is hard to gauge how typical Google's experience
is. Three other states have passed laws welcoming self-driving cars onto their
roads. Regulators in Nevada, Michigan and Florida said they were not aware of
any accidents. As self-driving cars proliferate, others issues will arise that
human drivers have dealt with for decades, notably who's liable for an
accident. Each test car is required to have $5 million insurance. Interest in
accidents will remain high, especially if the self-driving car is at fault,
said Bryant Walker Smith, a law professor at the University of South Carolina
who has written extensively on the technology. "For a lot of reasons,"
Smith said, "more might be expected of these test vehicles and of the
companies that are deploying them and the drivers that are supervising them
than we might expect of a 17-year-old driver in a 10-year-old car.
