The truth is that between the ages of 16 and 18, is the ideal sensitive period to learn how to drive, grow in responsibility, social justice, help others, friendship; so it is the perfect time - see my previous post on "When to teach what?"
Driving is not only transporting yourself on a car from one place to another, it is the responsibility that you have to do it well for your own safety and the safety of others: the ones in your car and the ones sharing the road with you. It is respecting the law and following the rules.
Concentration, NO texting, NO drinking and driving, NO speeding, returning the car home with a full tank of gas and on time are obvious rules that MUST be followed. Driving can be fun, but it also means helping with home errands and carpools and being thankful to your parents for giving you the privilege of letting you drive. The 'privilege of driving', as the sign at the DMV says, is something you earn and you must understand its meaning.
We must start early, building trust so when the time comes, he or she can be a safe, responsible an excellent driver. Good luck!
