I am wondering what were the speeds involved in the crash. The pillars look like they were made of paper in the aftermath. It depends on the speed though, but I think the car should have held itself better in case of normal collision speeds of around 80 kph. The pillars should not have bended in such a manner. May be it is because of the head on nature of the collision.
Anyhow, I do often wonder if some accidental, repaired cars are responsible for deaths in some of the cases. Not implying it is the case here, just saying that it is possible in some cases that a car whose pillar, or front crash beam etc is repaired, and it gets into a major accident, how much would that repair hold in such a scenario? All the safety features go down the drain if the body can't hold itself together. I once saw a Vezel being repaired in such a way. It had a major hit in the front, from Japan, and probably totalled there, and here some pieces of metal were being welded to make it look like total 'jenyan' before being sold to an unassuming customer.
