The statistics had been published by Google’s Waymo, that develops own self-driving cars technology and performs real-life tests of such cars on public roads. Today Waymo’s fleet has over 600 cars and over the half of 4 million miles had been driven during last year – although the road tests are being performed since 2009.

What is interesting, only a little more than 10 road accidents involving Google and Waymo cars happened during that period. Moreover, only one crash was due to the self-driving car fault: while changing lane in order to pass the roadwork, autonomous Lexus RX considered the bus on a neighbouring lane to be giving way when it wasn’t true.

Google claims that they have corrected the self-driving system software after the accident. All other cases of road accidents involving company’s test fleet were caused by human drivers.
