Of the nearly 50 self-driving cars rolling around California roads and highways, four have had accidents since September.

That was when the state officially began permitting the cars of the future, which use sensors and computing power to manoeuvre around traffic.

Three accidents involved Lexus SUVs run by Google. The fourth was an Audi retrofitted by parts supplier Delphi Automotive. Google and Delphi said the accidents were minor and their cars were not at fault.
