Sorry but I don't believe that all You 18+ didn't touch the wheel before being under 18 years old. I was teached by father how the car works, how to use it and how to drive it, when I was very young.
When teenager is talking about ultra-speeds reached in parents car, yes, maybe he is lying, but maybe not. Just look at this video:

He has proven his moron driving, but well, he is in jail now....
If you give a 13yo boy a fast car and straight road, why can't he reach 0-200-0km/h being still alive? And why Falcon can't drive his parent's car (under their control - maybe) in countryside. 99% that it's auto grbx, so what's the problem to practise? Sometimes it is illegal, but now I feel very-very safer, when I drive, than I could be just after shitty driving lessons, which teach how to park backwards in parallel parking (maybe 3 times in my life after driving exams
illepall) and driving 30km/h, 5cm near end of the road. It's crap.
If you know where to teach your son to drive, there is no problem. It must not be city center, and it's mad to scream about danger about teenager learning to drive a car.
If I were 'fresh meat' before driving lessons, I should die more times, than years I live.
