0.00 is too hard to attain. There can be alcohol in cooking and baking. Doesn't vanilla essence have a percentage of alcohol in it? There is also mouth wash, etc.
Any of those things can tip someone over 0.00, and then you might find people who haven't even had a drink being penalised for it.
I am more worried about someone driving with sleep deprivation (like a mum with a newborn dropping her other kids off at school) causing an accident, than l am of someone who had 1 glass of wine with a meal.
