vacation went from almost deadly to lost to saved

I do all of the driving until it is time to park then she gets behind the wheel and I direct her into the spot. I have many years directing aircraft movement and am a good judge of turn angles and anticipating movements. Things she just can't do. She steers, I tell her which direction and how much to turn the wheel and we slide it in. We have been doing this for at least 5 years now and I can't remember not getting it where we wanted the first time.
