Google's self-driving car may be written as a success story but since the commencement of the car testing 6 years ago, it has been involved in 11 accidents even though google only reported 3. All the accidents are not google's fault and her minor with no injuries. 7 of the 11 accidents was a hit from behind.
Google’s self-driving car program, Chris Urmson, said ''We’ve been hit from behind seven times, mainly at traffic lights but also on the freeway. We’ve also been side-swiped a couple of times and hit by a car rolling through a stop sign.”
