New cars that can steer and brake themselves may lull drivers into a false sense of security. One way to keep people alert may be providing distractions that are now illegal, just one surprising finding from Stanford University research that studied the behavior of students in a self-driving car simulator.(AP Photo/Tony Avelar, File)

The self-driving cars needed some old-fashioned human intervention to avoid some crashes during testing on California roads, the company revealed Tuesday, Jan. 12, 2016, results it says are encouraging but show the technology has yet to reach the goal of not needing someone behind the wheel.

Of the nearly 50 self-driving cars rolling around California roads and highways, four have gotten into accidents since September, 2014. That's when the state officially began permitting these cars of the future, which use sensors and computing power to maneuver around traffic. Three accidents involved Lexus SUVs run by Google Inc. The fourth was an Audi retrofitted by the parts supplier Delphi Automotive. Google and Delphi said the accidents were minor and their cars were not at fault.(AP Photo/Eric Risberg, File)

Google will release monthly reports on the performance of its self-driving cars, and it disclosed summaries of the accidents that involved the vehicles. The company said Friday, June 5, 2015, as it has in the past, that its cars were not to blame for any of the accidents. (AP Photo/Eric Risberg, File)

From left is project direct Chris Urmson, Brian Torcellini, Dimitri Dolgov, Andrew Chatham and Ron Medford, the director of safety for the project. Four years ago, the Google team developing cars which can drive themselves became convinced that, sooner than later, the technology would be ready for the masses. There was just one problem: Driverless cars almost certainly were illegal. (AP Photo/Eric Risberg)

Google engineers say they have turned a corner in their pursuit of creating a car that can drive itself. Test cars have been able to navigate freeways comfortably for a few years. On Monday, April 28, 2014, Google said the cars can now negotiate thousands of urban situations that would have stumped them a year or two ago. (AP Photo/Eric Risberg, File)

The legislation will open the way for driverless cars in the state. Google, which has been developing autonomous car technology and lobbying for the legislation has a fleet of driverless cars that has logged more than 300,000 miles (482,780 kilometers) of self-driving on California roads.
