Well since my daughter just started driving on her own this week I have some recent experience with this topic. First off I would agree that a driving school is the best, but even then you will need to take him out driving as (at least here in Washington state) you need to have 50 hours behind the wheel, including 10 hours at night with a licensed driver. And it takes awhile to get 50 hours which actually surprised me.
But having the driving instructor say the same thing you say, does reinforce it in the kids mind. It is amazing how an outside person validating your comments as a parent makes a difference in attitude.
Secondly you should contact your insurance company and see if they offer any kind of program. Ours did which involved tracking 20 drives and a sheet you fill out for each drive–but going through that program qualifies you for a good discount when your kid gets his license and you want to insure him. Also if your kid has good grades, etc that helps. Let’s put it this way–to add my daughter to our insurance was only $40 more a month on a 1994 Miata which shocked me as I was expecting it to be much more. But the age of the car, doing the insurance program, being a straight A student AND being a girl all helped her.
As for advice…hmmm…well be prepared to be critiqued on every little thing you do. They have eyes like hawks and any infraction you do will be pointed out. "you know you were supposed to signal there’ or ‘you do know that is actually not legal’ Just a heads up.
On Freeway driving we found a fairly isolated freeway section with two ramps about a mile apart. She drove back and forth for over an hour, merging then exiting, then merging then exiting. She is good at it now. Same with parallel parking, she is great at it. But she practiced a lot.
I did teach her how to drive a clutch because two of the three cars I own have clutches, but I also think it is an important skill everyone should have. That wasn’t the easiest thing I have ever done, but she is pretty damn good at it now, so it was worth teaching her.
All in all it wasn’t that bad of an experience. I am still nervous about her driving, but each day she has more and more experience. I took her out Wednesday evening to get gas as she had never done that. So now she knows how and I will admit I was rather impressed with her driving that evening. Much improved since the last time even.
I just got back from the gym and I passed her going the opposite way to school. I was oddly proud of her for some reason. Good luck!
