Not how you'd expect her to die

Your view is so obstructed that you can't see anything? Not even with mirrors? Then open the door, go out, and check!

Yes, because of course whether someone's behind you cannot change between when you do that and when you've got back in the car, buckled up, cranked the engine...

I'm sorry, but my mother's been driving a Mitsubishi Pajero for the last 15-20 years, never backed into it, there isn't an unobstructed view of anything under about 3' from directly behind the vehicle, if you check you mirrors and actually look over your shoulder there's no excuse for hitting anything unless it's actively hiding behind your car.
