hurled from car

An uncle of mine had a fatal accident a few days ago he drove out of a curve for unexplained cause at night. So far not so bad but he was not strapped on and he flew out of the car. I know details as well as accident photos and I have not yet. Especially tragic it would have happened to him almost nothing if he had been strapped on so the police. My question now if the car overturns and you are strapped on, then you can own I don’t want to hear threads like myself to blame the trottel or I’m sorry for your uncle etc.
