Chris Urmson, the leader of Google’s Self-Driving Car Program, presented research at a recent robotics conference in Santa Clara, Calif., that show Google’s self-driving Prius and Lexus cars are safer and smoother when steering themselves than when a human takes the wheel.
His statements come from analyzing data gathered from Google’s self-driving Prius and Lexus cars over hundreds of thousands of actual road miles in California and Nevada. One analysis showed that when a human was behind the wheel, Google’s cars accelerated and braked significantly more sharply than they did when piloting themselves. Another showed that the cars’ software was much better at maintaining a safe distance from the vehicle ahead than the human drivers were.
Google has been testing its cars on public roads since 2010, always with a human in the driver’s seat who can take over if necessary.
“We’re spending less time in near-collision states,” said Urmson. “Our car is driving more smoothly and more safely than our trained professional drivers.” Urmson also showed a new dashboard display that his group has developed to help people understand what an autonomous car is doing and when they might want to take over.
Urmson dismissed claims that legal and regulatory problems pose a major barrier to cars that are completely autonomous. He pointed out that California, Nevada, and Florida have already adjusted their laws to allow tests of self-driving cars. And existing product liability laws make it clear that a car’s manufacturer would be at fault if the car caused a crash, he said. He also said that when the inevitable accidents do occur, the data autonomous cars collect in order to navigate will provide a powerful and accurate picture of exactly who was responsible.
Urmson showed data from a Google car that was rear-ended in traffic by another driver. Examining the car’s annotated map of its surroundings clearly showed that the Google vehicle smoothly halted before being struck by the other vehicle. “We don’t have to rely on eyewitnesses who can’t be trusted as to what happened — we actually have the data,” he said. “The guy around us wasn’t paying enough attention. The data will set you free.”
I continue to think that the implications for the insurance industry over the next 10 years from this technology development will be significant.
