Seems the norm is many places. I think it has been the law of the land for 40 years in California and nobody seems to care. having friend getting a DUI for trying to do the sleep it off instead of driving home seems like a standard coming of age story.

If anything, the consensus is we need harsher DUI laws and enforcement.

There are a lot of poorly drafted laws on the books that people don't care about because the nefarious edge case isn't widely enforced. That doesn't make them good laws, it makes them quietly dangerous laws.

Also, in general any kind of "people support harsher X" where X is Think Of The Children-related will be true, but that's a heuristic for discovering bad laws that should be repealed because of the known effect that Think Of The Children rhetoric causes people to support bad laws.
