Very sorry Sue. Sometimes our SUV's can become a kind of "self contained environment". They've got good sound systems, lots of fancy instruments on the dash panel, digital controls for the temperature, a talking GPS system. You name it.
It's possible to get so focused with all this internal stuff inside the SUV, that you can kinda' lose contact with the outside world. I don't know if this is what really happened to the driver in the accident, but it's one possibility.
Anyway - sorry and prayers.
