No, you may NOT borrow the car.
How nice. I got my license when I got married as my abusive mother used my lack of wheels as control.
And you are an overprotective parent.
Nope. The oldest was a daredevil and I wasn't stupid enough to get him his license. The middle one had to be forced to get a license as he wasn't interested. He still hates driving. And the oldest is still a daredevil.
