I'm aware of the issue of inexperience and accidents (you're saying it's youth, I think that you introduce someone at 40 to driving their first few years will be as risky as your average sixteen year old). And I agree with that – one could make a case for yearly testing until five years of active driving.
However, there's also the issue of aging and its ravages on perception. One could say that, at fifty, I'm slower on things than a twenty year old would be; however with experience I can anticipate and move in ways that the twenty year old wouldn't be able to. Add another twenty years to me, however, and I wouldn't be surprised that the physical decay would overcome the mental practice and I'd find myself going slower and making mistakes.
Plus, the accidents change from someone acting overconfidently to simple mistakes.
There's a reason why Florida is so unsafe – lots of older drivers, lots of simple mistakes that don't get corrected because the old drivers are still trying to react
