That's how it is here in Japan by law - zero tolerance, even one drink is too many.

One solution is "daikou" taxis - they drive you home in your own car, with a chase car to bring the driver back. Where I live they're subsidized (volunteers I think) and can actually be cheaper than a taxi https://ja.wikipedia.org/wiki/運転代行 (use your browsers translate tool)

Public transportation exists if you cannot fight the alcoholic urge to drink.

Is this sarcasm? I honestly can't tell. Drinking and driving is obviously not OK and deserves at least huge fines, so I don't get your point.
