He's insured.
That said, his rates are about to go up. God only knows how he wound up in this configuration or why the Prius is in the part of the road that it is?
Even I have enough insurance to cover all of the damage I see in the photos. And the woman in the Prius, (who may be found at fault), was not seriously injured. Look at the photos...he obviously jerked his steering wheel to the left to avoid her and would up lifting the right side of his battleship as he hit her. There is very little evidence of impact on the Prius, he just sort of drove up onto her hood at low speed.
