Heh...another true anecdote. Our widow neighbour came over for dinner a couple of months ago, and for reasons best known only to her, drove up our somewhat (less) steepish driveway.
After dinner,and already getting dark, said neighbour says goodby and heads out to her car, a hybrid with all the bells and whistles.
Wifey is watching her and suddenly realizes that this person is going to back down our 'S' curved driveway, with a steep dropoff on the East side. She yells out to me to get my butt out there and stop her before she rolls her new car.
Sure enough, instead of using the senses she was born with, she's trying to back down using only her rear view camera and monitor...and heading straight for the drop-off!
I ran down the driveway like a crazy person and stopped her in time; she literally couldn't figure out how to use her wing mirror and common sense.
(same person backed into another neighbour's car...using the aforementioned rear-view camera and monitor....twice.)
