Yeesh. That's got to be quite stressful... may this man rest in peace. I remember when a car got flipped about fifty feet from our doorstep because it was t-boned by another speeding car. Paramedics arrived within moments, along with about 20 people, and they got the person out of the upside-down car very quickly. The noise was unholy... you ever scratch your fingernails on a chalkboard? That, much lower in tone, much louder, plus tire screech and metal thudding and rolling.
