Your assuming you know the height of that particular stinger. In order to know that you need to know what suspension,size tires, and exact bumper it is,, then you need to be clairvoyant as to weather the collision occurred while the jeep driver was on the gas or emergency braking,,, because when you slam on your brakes,, the front end dips significantly. Also,, if the stinger was forward of the victim at time of impact,, remember, the white sedan is not stagnant,, it is also moving forward, which is why you see deeper penetration at the door,, then it gets shallower toward back half of the car. also,, as the driver is moving forward, lets assume she is centered in her seat, as most of us drive. At the moment of impact her car rapidly moves toward the passenger side. Her body and head are not attached to the car in such a fashion that she moves that way also,, so at the speed of the collision her head would have moved rapidly toward the glass of the door.(This is why automakers developed side curtains) If her head went straight toward the window,, at the same time the stinger was coming through the window,, there is no way the air bag could have stopped it,, not counting the fact that if the stinger was through the window first,, that would not have set off the side curtain, the side air bag would not deploy till the main body of the bumper struck the car.
Now please tell me where anything I said does not make sense.
