Condolonces to you, and indirectly to the family of this woman. A tragedy, to be sure.
However, this does point out why it is important, even on an automatic, to set the parking brake as well as putting the transmission in Park.
Often times the only thing you want to do is get away from the wasp. If she were allergic to wasp stings, the fear of that may have overrode her common sense. Cant monday morning quarteback this play.
My condolences to friends and family on this horrific accident.
I prefer to never get in front of or behind a car with a running engine. Make sure the brake is set, it is in park and the engine is off.
