Those with older kids, do they drive?
My kids are 22, 19, and 16. They all got their licenses as soon as they could, and when they had permits, I made them drive everywhere. But my youngest, her friends are 17 (she has a late birthday) and none of them have licenses. The parents won't let them get them, or the kids have no interest. Even my older kids' friends were 18+ when they got theirs, and my oldest has friends who still don't have one.
I remember in highschool what a big deal it was to get your driver's license. The day you took your driver's test was an excused day off at my school.
