Cognitive ability is a far better test. I used to be a raging alco, like real alco, not just daily drinker. The levels I functioned at would kill most people.
Of course I still have alcoholism, but I haven’t drank in 12+ years. While I don’t condone drinking and driving at all - in fact it makes no sense at all in this age of ride sharing - but if I were on a jury I could be swayed by a heavy drinker excuse. 🤷♂️
