According to the articke, autonomous car (unclear so far if manually controlled at the time of the accident or not at the moment) hit car A (old lady), car A subsequently hit car B, car B went of the road, hit a tree and caught fire. After hitting car A, the autonomous car hit car C head on (I assume that's what you see in the picture), driver of car C died (no surpise whej looking at the picture). Pretty fucked up, even more so if the autonomous car was actually driving autonomous.

For what it's worth, the autonomous car in question seems to be a BMW (hard to tell with the wreackage).
