Vehicle cashes are one of the primary causes of death for certain age groups. Tens of thousands of Americans died from them each year. Countless thousands more are injured. Drunk driving isn’t a “what if”, it is a regular occurrence that causes a significant fraction of these crashes

The comment I replied to said that the various ways this technology/regulation could have harmful effects were theoretical "what if" scenarios. I pointed out that the ways it could have beneficial effects are also theoretical "what if" scenarios. I'm not saying that people dying because of drunk driving is "what if", I'm saying that this technology/regulation preventing drunk driving is just as much of a "what if" as it doing anything else. Just because something is advertised as having certain effects by its proponents doesn't mean it actually has those effects.

It is not, because the technology exists, and it works. Unless you are doubting that it actually works, which you seem reluctant to commit to.

there are multiple comments in this thread attesting to the fact that these detection systems often don't work.
