The point I was trying to make is that the law does recognize that not everyone who drinks alcohol becomes a drunk (i.e. .08 BAL) , I was just stating that the person that drinks 2 beers, in most cases, isn't impaired, but has to suffer the same consequences as the jackass that chose to binge drink and drive. You're more likely to get killed by a texting teenager than someone who grabbed a couple beers with dinner.
Well then, let me give you something to ponder that's even worse for "casual" dinner drinkers. You are having lunch on Friday with your bud, you both drink 2 maybe 3 beers with your meal. You both leave in separate vehicles. While you are driving through a neighborhood on your way back to work, a little kid runs right in front of you chasing the ball his brother accidentally threw into the street. You kill the child. It all looks like a helpless tragic accident that couldn't be avoided. But then the cops smell a tinge of alcohol on your breath while they are interviewing you. Oh oh! Guess what? Those 3 beers may cost you everything.
Do you think the kid is any less dead because you had 3 beers as opposed to 12? You get the point.
