You'd be surprised at the accidents like that, where they actually live. DH will call me when he's on a run to tell me it's a rollover and I always expect to hear that the person(s) died. 85% of the time, they live.
DH's firestation is right off of I-45 in Houston, and he picks up a lot of MVA's when he's on tour. Very rarely will he go into detail, but a few that he has told me about... ooooo, it's bad stuff.
A few accidents have stuck with him; it's the fires that will eat him up inside.
