In fact, Urmson writes, Google’s self-driving cars have logged some 1.7 million miles over the six-year life of the project, and they’ve been involved in a grand total of 11 accidents. Not one has been serious. More importantly, if you believe Google, not a single one of those accidents was caused by the self-driving car. Eleven minor accidents in 1.7 million miles is a much less alarming ratio. And, Google noted, comparing it to the national average may be misleading, since a great many minor accidents go unreported.<\/p>\n<\/div>\n
\n
Oh, and zero accidents caused<\/em> in 1.7 million miles is obviously a strong record by any standard.<\/p>\n<\/div>\n\n
So what’s the takeaway here? Are Google’s robot Lexuses super-safe or super-scary? The answer, actually, is the same as it\u2019s been all along: As far as we know, they’re really quite safe – but to render a verdict would still be premature.<\/p>\n<\/div>\n
\n
For one thing, we assume Google is telling the truth and not fudging its figures. But it would be nice, if we’re going to trust these things with our lives in the foreseeable future, to be able to verify such assertions with something other than the occasional anonymously sourced investigative AP story.<\/p>\n<\/div>\n
\n
Meanwhile, there’s another confounding factor in these numbers that’s often overlooked. When a Google employee behind the wheel of a self-driving car sees a risky situation developing, her instructions are to take the wheel herself. That means Google’s cars don’t even have a chance to cause an accident unless the person behind the wheel fails at her job first. No wonder crashes in autonomous mode are rare!<\/p>\n<\/div>\n
\n
Now, whenever this happens, Google takes the car back to its shop and simulates what would have happened if the driver hadn’t taken over. In every case, Google says, the simulations show that the car would have automatically avoided causing the accident.<\/p>\n<\/div>\n
\n
That’s reassuring if true, but there also seems to be some circularity at work here. Remember, these are Google’s own computer simulations we’re talking about-presumably, using the same assumptions that are built into the car itself. How can we be sure the simulations aren’t mistaken?<\/p>\n<\/div>\n
\n
To recap, here\u2019s what we can say with confidence: Self-driving cars are not running amok and causing accidents at an alarming rate. If anything, they appear to be excellent drivers based on the limited evidence we have so far. By the same token, they will not save you from all the other idiots who populate our nation\u2019s fair roadways.<\/p>\n<\/div>\n
\n
What we cannot say with confidence yet is whether self-driving cars will in practice substantially reduce the rate of traffic accidents in a world where they share the road-and sometimes, the wheel-with human drivers. Which is a very good argument for exactly the kind of road testing that California and several other states are now permitting on their public roads. It\u2019s also a good argument for a little more transparency as to how those self-driving cars are performing.<\/p>\n

An exclusive Associated Press report Monday revealed that four self-driving cars have been involved in fender benders on California’s streets just since September. That\u2019s out of a total of fewer than 50 legally permitted self-driving cars on the state\u2019s public roadways.
