Still, as I age and watch others around me age, I think a BDR as in
biannual Driving review would be worth considering. Or, maybe, some
kind of reaction time test required of a driver before the car would
start.

Some people become significantly impaired in old age (old in this case meaning
well beyond 65), but then again, some are impaired even in youth. Certainly
an objective test is the best way to identify impairment, rather than a
default assumption based on age. The same could be said to a lesser extent of
impairment due to drugs, but since drugs such as alcohol are pretty much
universally impairing and objective on-the-spot tests are difficult to
conduct, sometimes default estimations are made for expediency and safety.

Personally, I don't understand why so many people here are defending the
consumption of alcohol while operating vehicles, especially aircraft. It's an
incredibly stupid thing to do. Should I assume that many people here are
incredibly stupid?
