The accident was a head-on collision for the Nissan Leaf and listed as a rear-end collision for the Apple autonomous vehicle.
According to a California DMV report (PDF), Apple's self-driving auto, in this case a modified Lexus RX 450h, had such an accident just last week.
According to previous reports, Apple has been testing its self-driving software in Lexus RX450h SUVs in Cupertino, California and surrounding areas since early 2017, but an accident was never reported, until now.
The crash occurred just before 3 p.m. on August 24 in Santa Clara, close to Apple's headquarters in nearby Cupertino, during autonomous testing. The accident occurred on August 24th at 2:58 p.m. when Apple's autonomous vehicle was "preparing to merge onto Lawrence Expressway South from Kifer Road".
Apple has never publicly spoken about its self-driving auto project.
While both the involved vehicles suffered damage, no one was injured.
Uber also faced a similar incident on March this year, which led to it shutting down the project in Arizona two months after a fatal crash involving one of its vehicle.
The accident of Apple's secretive vehicle took place on August 24.
The DMV has approved 56 companies to test self-driving vehicles on California roads.
Details about the incident surfaced in an autonomous vehicle collision report filed with the State of California Department of Motor Vehicles. Waymo's vehicles, for instance, tend to stop before turning, crossing an/merging onto intersection, and to give way to pedestrians.
