This is because alcohol impairs your judgement and reflexes - and when you're driving a 1 tonne piece of metal that can maim and kill, you want your wits about you.
I confess I find this kind of reasoning very bizarre - I truly do admire the US, and all the freedoms, literature, and amazing critical thought it's given to us. But I still don't understand the strange logic that seems to emanate from certain circles - where people will sincerely claim it's their God-given right to drive over the speed limit and kill people, to take drugs and kill people, to shoot guns and kill people, and other such things.
It's also in this context I hear people from the US complaining a lot about the "nanny-state".
Or that somehow, if the government provides any modicum of healthcare, you are infringing on their God-given right to make really poor healthcare spending decisions.
I get it there's happy medium between the two - and I apologise if there's hyperbole in the above - but as an outsider looking at how the US has handled the COVID-19 pandemic - it's heart-wrenching.
As a country, you have nearly 100,000 people dead (the worst in the world I think?) - and people are still talking about how "mask wearing is oppression", or "lockdowns are trampling on our rights!".
Even your leaders - if the press can be believed - apparently see wearing a mask as a sign of weakness. Yet other governments (e.g. UK, Australia, Scotland) have sacked high-level ministers, simply because they breached the health lockdown rules. It's the complete opposite - those governments are taking it seriously (or at least trying to be seen to be).
