My youngest sister has her learner's permit so I've been trying to teach her how to drive. You don't know true terror until you're in the passenger's seat of a 16 year old's car
I'm dealing with the same thing right now! I had to teach her how to parralel park yesterday! It is terrifying! 
Oh heck, I can just barely parallel park. I'm dreading teaching my sister that one, oh boy..
You can take her to the DMV when they are closed! They will allow you to use there set up to help.
