Back to the subject……
Amazing experience and I am glad you were in a pick-up. What could she have done to you in the vehicle if she had made contact?
Don't really want to think about that. I've seen bluff charges before, and they're generally characterised by a lot of display (huffing, jaw clacking, pounding the ground as they run, the ears are held up, and the animal doesn't look at you). This, in my opinion, was the real deal; she was looking straight at me, and was coming straight for the drivers window, she was totally silent with no "display", and her ears were flat against her head. Whatever was going to happen, I just don't know, but I beleive it wold have ended with some form of physical contact with the vehicle. Chances are, with a defensive aggressive act, it would have been quick, but with a reasonably large bear (300 or so lbs) she would have been very capable of inflicting a bit of damge to the vehicle and me in that short period.
