CMV: Drunk driving laws (in the US) are absurd and unjust, and need to be fundamentally reformed

0.0799999 BAC: you've done nothing wrong, you're free to go. 
0.0800000 BAC: You're a fucking disgusting excuse for a human being, hope you enjoy rotting in prison and paying $10,000 in legal fees. Your life will be destroyed because you risked destroying others. 

I am not in favor of drunk driving. Im aware of how many people are killed by it. But being against it doesn't mean being in favor of the irrational way we enforce laws against it. We need a gradation of punishment, where the punishment is worse the higher your BAC. A basic principle of justice is that the punishment must fit the crime. If driving around with a 0.07999 BAC is considered just fine in the eyes of the law, then we shouldn't go from zero punishment to extreme punishment when you add 0.0001 to that number. That approach might work by inspiring fear, but it isn't just. What if we did that for speed limits? Zero punishment for going up to 20mph over the speed limit, instant felony for going 21 mph over? Sure  most people would be terrified of speeding in that case. But you're sending confusing messages by saying its perfectly okay to speed as long as its not 21mph over. And some people, the less cautious ones, will speed anyway thinking they can keep themselves from going over 21. Then bam, felony. Is that any way a just law? I think not. 

Also, the speeding law I described would actually be more just than drunk driving laws, because at least you know when you're speeding. You can only guess at your BAC, subjectively estimating how drunk you are. First, most people have no idea what subjective feeling of drunkness corresponds to a BAC of 0.08. They have to resort to doing math in their heads: "let's see 3 beers 4 hours ago , plus one shot 2 hours ago, but I ate food with it so it had less of an effect..." Secondly some people with high tolerance may not even feel much at all when their BAC is 0.08, and they may feel like and actually are okay to drive. 

Imagine my speeding law scenerio where there is no such thing as a speedometer, and you have to guess how fast you're going. Then it would be really fair to charge someone with a felony for going 21mph over right? 

This is what we should do: have graded punishments with increasing severity for higher BAC. And mandate breathalyzer installation on all cars so that everyone knows exactly whether they are breaking the law or not before starting the ignition.

That's not actually true. A police officer can still arrest you for a DUI even if you blow under .08. It's up to their discretion when you blow under .08, but it's a guaranteed DUI if you blow over.
