Backseat Driver

So today while we were in the car, I was starting to take a right-hand turn at a red light. From the backseat, I hear a desperate "NO MOMMA - DON'T DRIVE YET!!". Then Caitlin proceeded to tell me that "Red means stop, wait for green to go."...duh, Momma.
I tried my best to explain the right on red concept but I don't think she was buying it.
