Most places i feel you can get away with riding drunk. Not swervey drunk, but more intoxicated than you should drive in a car. I don’t feel cops really care too much for drunk cyclists.
I mention this, because some people drive drunk in a 2 ton vehicle capable for killing or maiming others. Those same drivers on a bicycle would be better (though there’s still a chance for injury and death, more of that risk is to the rider than others)
Even then, another bonus with biking vs drinking and driving, you can get off your bike and walk home with your bike. With cars you can’t do the same, and, at least in my area, there a lot of times you can leave your car overnight at places. So there’s a huge incentive to drive it or pay for a ticket (which of course, pay the ticket over a DUI, but still).
