Even if it’s accuracy was not that great, say <25%, 25-75%, and >75% of legal limit would still be useful to know as some places have heavy handed bartenders, were you could end up with more than your expecting if you are counting drinks. Even having crude data will let me know how fast various formats of alcohol are uptaked and processed out so if I have a drink with friends, I would know ahead of time if I should take transit vs walk in park after and then drive or stick to alcohol-free drinks (most people I know are cross town in a way public transportation is not cheap/quick but a car is). Edit: I do use a breathalyzer on myself now, but they are annoying to take samples, and are not super accurate either
