True. Well you know what I mean I am sure.

If the legal blood percentage in X % in Europe, Americas, etc. that means it is probably safe to have some alcohol in your blood and still drive. Just because you've had a couple glasses of wine, doesnt mean you are incompetent to drive. If you're a big man, that wine would not affect you much and you would likely be below X % of alcohol in your blood. It would be just as dangerous, or more, if you were driving while tired and sleepy.

Don't argue with me just for the hell of it.
