The problem with alcohol is that accidents involving at least one drunk party are vastly more dangerous.
I can only quote German numbers from
here:
For the whole of Germany in 2015, focusing on traffic accidents only:
For every 1000 accidents resulting in bodily harm, alcohol-related cases resulted in 19 deaths and 347 heavily injured.
The average across the board is 11 deaths and 222 heavily injured per 1000 accidents resulting in injury or worse.
So nearly twice as many deaths and roughly 50% more heavily wounded people each.
7.4% of all deaths in accidents involve alcohol. That's a disproportionately huge amount.
And that's at the 0.05/0.03% legal limit, as outlined in my earlier post.
In Germany, around 1.5% of all accidents total, and 4.1% of all accidents resulting in injury involved drugs (including alcohol). So another significant boost there. More than double, close to triple.
Really, don't drink and drive, even if you think you're still good to go. It's the safest choice - you just don't realise how impaired you are.
If you absolutely must, stop after two beers at most (and make sure you also eat something alongside while taking your time). Afterwards, keep to one beer or less per hour (or the equivalent in alcoholic beverages). That's a very rough approximation, mind. However, it's not terribly restrictive. And frankly,
ideally you'd let someone else drive you home at that point, anyway. I know it's not always practical, but do strive to keep your fellow countrymen out of harms way, please. And yourself. But that's a given, I hope.
