Google and Delphi Automotive are responsible for the self-driving test vehicles involved in the minor collisions. Three of the 23 Lexus SUVs that Google modified into “autonomous driving” rigs and a self-driving test vehicle belonging to Delphi Automotive crashed in separate incidents. Both companies dismissed the bangups as minor and claim their cars aren’t to blame. It’s worth noting that drivers are still required to be behind the wheel when in motion in California. The accidents came to light after the AP confirmed that California DMV records for the incidents existed.
