As an instructor in driver education at the local area High School, I've learned that even the brightest students can become flustered behind the wheel.
One day I had three beginners in the car, each scheduled to drive for 30 minutes.
When the first student had completed her time, I asked her to change places with one of the others.
Gripping the wheel tightly and staring straight ahead, she asked in a shaky voice, "Should I stop the car first?"
