If that is indeed what they're saying, my point still stands. The blood alcohol limit has no variations for age, sex, gender, race, weight, time since last usage, or any other factor. It just goes by concentration. My point still stands. What the law considers the concentration which indicates intoxication is a metric based on what is considered an acceptable level of risk.
