Self-Driving Cars In California: 4 Out of 48 Have Accidents, None Their Fault 408
An anonymous reader writes: The Associated Press reports that 48 self-driving cars have been navigating the roads of California since the state began issuing permits last year. Of those, only four have been in accidents, and none of the accidents were the fault of the autonomous driving technology. Seven different companies have tested autonomous cars on California's roads, but Google, which is responsible for almost half of them, was involved in three of the four accidents — the other one happened to a car from Delphi Automotive. All four of the accidents happened at speeds of under 10 mph, and human drivers were in control during two of them. The Delphi accident happened when another car broadsided it while its human driver was waiting to make a left turn.
The AP pieced together its report from the DMV and people who saw the accident reports. But critics note that there aren't direct channels to find this information. Since one of the chief selling points of autonomous cars is their relative safety over cars piloted by humans, the lack of official transparency is troubling. "Google, which has 23 Lexus SUVs, would not discuss its three accidents in detail." Instead, the company affirmed its cars' accidents were "a handful of minor fender-benders, light damage, no injuries, so far caused by human error and inattention."

Not necessarily. Pick a pool of 48 cars at random and compare the accident rates. You also have to compare them by the accident rate per hour behind the wheel.
This gets at the whole idea that self-driving cars have to meet some lofty standard of perfection to become the optimum choice. To replace people behind the wheel self-driving cars only need to be +1 better than human drivers.
Self driving cars can't drive in the rain. Oh, really? Take a drive around Seattle in the rain, you'll discover human drivers suck in the rain, too. And that's in the rain capitol of the world where you'd expect people to be used to driving in the rain and they still suck (I lived there for 10 years so don't bother trying to deny it).
