Accident at “right in front of left” Guilt question and recognition of guilt

Hello everybody, my wife happened a stupid accident today. She didn’t pay attention to it in a 30’s zone to the left… Actually the question of guilt should be clarified, but she didn’t drive into the cars coming from the right, but the car hit her in the back right (from half rear tires). Furthermore, the opponent managed to turn with a small Peugeot 107n heavy Alfa 156 by 180 degrees… What seems funny to me is this turn (to snatch it) ell was in a 30’s zone?) and the hit back right (lack of care when driving at “right in front of left”?). Ohso, something funny… Since the accident happened in the community, she immediately took her son who then took photos. My wife wanted to call the police, but then the son said that it only costs fines… An hour later the woman stood in the door and held a debt recognition in his hand… Well, I was there, of course, was not under Since it’s an older lady, I don’t want to think about a planned accident, but I know her and I know how she drives like that. Is the question whether it’s really 100% just our damage, or it’s a partial fault, because the damage to our Alfa is not insignificant and unfortunately we only have a partial cascade. Greeting, Sven
