Google has admitted that its self-driving car has been involved in 11 minor accidents since the inception of the project six years ago.
The search giant said that the accidents occurred during the 1.7 million miles of autonomous and manual driving with drivers inside the car.
However, it highlighted that none of the accidents were caused by its next generation vehicle.
According to Google, its cars were victim of rear-end crashes which accounted seven out of the 11 crashes reported.
The autonomous cars were hit from behind by other cars at traffic lights while in some cases they were side-swiped and hit by a car that rolled through a stop sign.
Backchannel reported Google self driving car programme director Chris Urmson as saying: "And as you might expect, we see more accidents per mile driven on city streets than on freeways; we were hit 8 times in many fewer miles of city driving.
"All the crazy experiences we’ve had on the road have been really valuable for our project."

The revelation came after a US based Consumer Watchdog asked Google to give details of the accidents that were filed with the California Department of Motor Vehicles.
The watchdog also asked Google to make public, the future driverless car accident reports.
Urmson added: "We’ll continue to drive thousands of miles so we can all better understand the all-too common incidents that cause many of us to dislike day-to-day driving? – ?and we’ll continue to work hard on developing a self-driving car that can shoulder this burden for us."
