A police officer made a traffic stop but wrote no ticket. There was no one actually driving the car - it was a Google self-driving car being tested on local roads in California.
The car was going 24 mph (38 kph) in a 35 mph zone and realized it was a Google Autonomous Vehicle. The officer stopped the car and contacted the person behind the wheel to say the vehicle was impeding traffic, but he didn't give out a citation. The Google project responded in a blog post, saying the cars have never received a ticket and adding, "Driving too slowly? Bet humans don't get pulled over for that too often."
The self-driving cars that Google has been testing on California's roads and highways were involved in 11 minor accidents over the past six years, according to the company.
The director of Google's self-driving car project wrote in a Web post that all 11 accidents were minor " "light damage, no injuries" " and happened over 1.7 million miles of testing, including nearly 1 million miles in self-driving mode. Google has said that self-driving cars were never at fault.
