In the USA today, people still seem to get their driver's licenses earlier than Europeans, as we have more of a car culture over here. But that gap is closing, since apparently fewer and fewer young Americans are gung-ho about driving or learning to drive these days, our rather persistent car culture and very limited public transportation notwithstanding.
Canada is probably the same way, despite also being a car culture with limited public transportation as well. And their drinking ages are 18 or 19 depending on the province. Meanwhile, their traffic fatality rates, both alcohol-related and otherwise, are in fact lower than those in the USA, in every age group in fact.
One can also say the same about Australia as well, whose drinking age is 18, is a car culture, and has even lower traffic fatality rates as well for all ages, both alcohol-related and otherwise.
And so while not completely irrelevant yet in that sense, the tired old drunk driving argument against lowering the drinking age to 18 is indeed far less relevant compared with the way it was one 1980s and 1990s. But honestly, the drunk driving argument never made sense to us. DUI is already illegal, and even more illegal now than it was in the 1980s. And doing so is dangerous at any age, not just under 21. And of course, it is perfectly possible to not mix alcohol and driving. Punishing all drinkers under some arbitrary age limit by depriving them of liberty on the mere supposition that they *might* get behind the wheel after driving (and thus in turn *might* harm innocent people) goes against everything a free society stands for, and is 100% un-American. And just like "flattening the curve", the best it does is kick the can down the road without actually solving anything. Studies by Dirscherl (2011), Miron and Tetelbaum (2009), Dee (2001), as well as Asch and Levy (1987 and 1990), et al., bear this fact out quite nicely.
Let America be America Again, and lower the drinking age to 18. If you're old enough to go to war, you're old enough to go to the bar. 'Nuff said.
