Well, they shouldn't have been driving on that obstacle. IIRC, she didn't even drive it up the obstacle... only down. I said that she shouldn't have been driving on it. Then combine it with a mechanical failure and it turns into a disaster.
Plain and simple, she shouldn't have been driving on it. An automatic vehicle without an emergency brake shouldn't have been on the hill. I'm willing to bet she panicked when it stalled and forgot to put it into neutral and couldn't get it started again.
Years later the lady "overcame" her fear on some TV show by driving it in a new Rubicon. Talk about being scatter-brained. I'd hate to know what she's like in a panic situation.
I'd like to believe that a seasoned wheeler would've handled it better. If not, we're in a world of trouble.
