A Google self-driving car was recently pulled over by an officer in California for speed. But, rather than being targeted for speeding, the empty car was noticed for driving a bit too slow.

Reports say the autonomous vehicle was traveling on local roads in Mountain View, California, and was seen by an officer driving at 24 mph in a 35 mph stretch of road.

The officer realized it was self-driving car and pulled it over. The officer then “made contact with the operators to learn more about how the car was choosing speeds along certain roadways and to educate the operators about impeding traffic,” according to a post on the police department’s blog.

The brains behind the bubble-topped buggies say it's another example of someone flagging them down to find out more information. Although, getting pulled over is a bit different than a curious commuter questioning the car's abilities.

Google officials add that the self-driving vehicles have now logged more than 1.2 million miles - a distance equal to about 90 years worth of driving for an average person -  all without being ticketed once.
