Back Seat Driver

I have been put in my place, repeatedly, by my two year old back seat driver. Jenna sits on the passenger side, so she has a clear view of me. About a week ago, as I was driving, I hear "Mommy! "One hand driving get you in accident! Use two hands!" With this, she puts up both her hands in the air as if she is holding onto a steering wheel. I replied, humbly, "Oh, OK Jenna. I'm sorry." as I put my other hand on the wheel. Now, every time she sees one of my hands come off the wheel, I am scolded in some way or the other and reminded of how I am going to get in an accident. I don't know where this came from. I have observed, however, that she doesn't seem to mind asking me to get her things while I am driving, therefore, requiring me to take a hand off the wheel to locate said object and then hand said object to her. Hmm, I guess the two-hand rule applies only at certain times!
