Four self-driving cars in California have been involved in minor car accidents since September, when the state began issuing test permits to self-driving car companies, according to AP.
Two of the accidents occurred when a real driver was behind the wheels of the autonomous cars, while the other two incidents were “not-at-fault” accidents while the computers were driving.
The accidents that occurred while the computers were driving both occurred at speeds below 16 kilometres per hour.
There are currently 48 autonomous cars testing on public roads in California.
Google said in a written statement that since September 2014, a “handful” of its self-driving cars have been involved in minor collisions near its headquarters due to “human error and inattention.”
Given that the one of the main selling points of the self-driving car is its supposed increased safety, accidents involving the vehicles receive a high level of attention from media.
