Hey stop w/all the complaining. To put it simply, if you can criticize a driving school, you ought to be able to take on the challenge yourself and teach your teen to drive.
I teach my grandson to first listen and then by listening to him, w/o interrupting each other.
He already is a big fan of my driving. For one thing, I as a rule do not multi task on this one activity. Not because it's the law, but because it's just not done. It's just plain stupid to give in to, weak moments and to have so many of them in a series, while performing one of the most important tasks you will everyday you drive. By that I mean driving, not texting.
I could go on but its too long and involved. Good Luck with your teen.
