The author of the article seems to be against a device that will save a lot of lifes and improve the quality of life to even more people to save $300.
If we had guts, we would ban bars from selling anyone more than three drinks, and ban bars from serving anyone who has had a drink anywhere else that day. (or something, I'm brainstorming).
Also how would you prevent other bars from selling to people without a centralized database.
Holding bars accountable.
TABC (Texas bar regulator) tells all bartenders TODAY that you cannot serve someone to excess (above 0.08% BAC) and cannot serve someone who is already drunk. I guarantee you that every single bartender in Texas has violated this regulation.
When the regulations step in with reality, and are enforced, maybe fewer people would be overserved.
