Mine learned to drive a long, long time ago, but if it was today, my first rule would be==CELL PHONE IN THE BACK FLOOR AT ALL TIMES. If you are ever seen by any of us or friends texting and driving, your car/my car will be parked for a month and you will walk or take the bus for that month.
I had volunteered for a long time in Emergency at our hospital and seen the bodies of barely alive young people being pushed past me to ER with doctors and nurses running....
A lot of our rules were more or less negotiable but driving ones were set in cement. And anyone else driving our cars would be the same, unless you were in the back seat bleeding and on the way to the hospital. All had some sort of medical training, even the school teacher met her husband in EMT classes.
CARS CAN KILL.
