Ecological viticulture: wine of econology?

[Exnihiloest]

...
This is also the argument used by the wine growers. When driving, there is no minimum dose (for some northern countries the minimum dose allowed is 0) since a single glass of wine already reduces reflexes ...

That's right, but it's irrelevant to prohibit it.
We are not equal neither for reflexes, nor for sight, nor for the judgment of situations etc. etc. When the variability of criteria between humans is much greater than the differences with "no alcohol / a drink", there is no there is no reason to forbid it. Or you have to test each one and ban driving to those who will pass the driving tests less well without having drunk, than the one who will have drunk a glass of wine 2 hours ago but will do better for a whole lot of reasons!

No prohibition, no more than an obligation, has made it possible to make individuals obedient to the injunctions of doing or not to do.
For alcohol, in question, the legislators, and therefore the policies, take into account each national particularity. A non-alcoholic country (no underlying economic interests) will be more severe than a wine country, more lax, and it does not depend on individuals in their personal consumption in private.
On the other hand, the fact of having had a drink and getting behind the wheel 2 hours later, that would actually limit accidents, but the reality is quite different since everything has to be policeed to limit the damage.
