I would caution that just because the 'talk' from Dad worked for you, that is no guarantee that it will work for others. In a similar vein, a case I know of.
Dad was a car nut and had a Chevy Nova SS 454. He loved that car. His son was an honor student that would make you proud - Scouts, Church, Grades, nice to puppies and old ladies, etc.
When son became 16 and got his license he asked Dad to drive the car for the first time. Dad said OK but only slowly in the neighborhood and no friends. The law found the kid and friends wrapped around a pole from a 100 mph crash, no one lived.
So I agree that till the kid reaches a more adult level (as above) unsupervised access is risky. Today's social media climate is scary.
