Funny you should talk about your wife like that retired engineer.
My grandson has a permit and every morning we go for a drive. He does great.
A couple of times, grandma went with us. Within two or three blocks, my grandson says " hey grandpa, you want to drive?"
Another good one was when my mother learned to drive, I was the teacher. I was 10 and she was 28.
We didn't have automatics back then and my father told her "one more burned out clutch and you will spend the rest of your life WALKING!"
Me and my mother still laugh about that. 4951
