Have you ever had to use one?
No. I don't drink.
This is the dumbest take.
Sure, because 32 drunk driving deaths every day is apparently not a problem for Lemmy neckbeards.
The camera would accurately detect drunk driving patterns, as well as sleepy drivers, dementia drivers, texting drivers, stoned drivers, drivers eating cereal and hot soup, applying makeup, all the stupid shit North American drivers do. If any of that affects your insurance, just don't fucking do that.
