A Google self-driving car has been involved in the worst accident so far involving one of the firm's autonomous vehicles.
The modified Lexus SUV had to be towed away after another driver jumped a red light at a junction and smashed up the passenger side door, causing the airbags to deploy and rendering it un-drivable. The car was subsequently taken away on the back of a flatbed truck.
The Google vehicle passed through a green light at an intersection in Mountain View, California when was it was rammed by the other car.
Once again, the accident wasn't the fault of the autonomous vehicle, but rather the human driver.
A Google spokesperson said that if anything the incident underlined just why driverless cars are required on the world's highways as they will reduce the number of accidents in which human error is to blame.
"A Google vehicle was travelling northbound on Phyllis Ave in Mountain View when a car heading westbound on El Camino Real ran a red light and collided with the right side of our vehicle," they told 9to5Google.
"Our light was green for at least six seconds before our car entered the intersection. Thousands of crashes happen every day on US roads, and red-light running is the leading cause of urban crashes in the US.
"Human error plays a role in 94 per cent of these crashes, which is why we’re developing fully self-driving technology to make our roads safer."
It is expected that the majority of cars will be self-driving within most readers' lifetimes, and many governments around the world have started trials of the technology, including in the UK.
It's not just tech vendors experimenting in this area. Jaguar Land Rover kicked off a multi-million pound autonomous vehicle research project earlier this year.
