Good for her, I'm glad she's alright.
But apart from the people in that forum, I account 50% of her safe-exit, and the other woman's injurys to the fact that She was in an SUV. The other 50% to the Airbags.

Just because it's a "BMW" doesn't make it safer, it's a combination of airbags, and body-engineering.
But either way, It's nice to know she's okay. Too often do I hear of fatal accidents, from less of an impact. It's good to know one got away.
nice find DerScotsman
