I too believe the drunk driving laws are getting ridiculous. And again the feds are to blame for a lot of it. They tie there money to keeping the states under control.
If you have an accident while drinking, absolutely through the book at them. If they kill someone while they're drinking and driving give them the death penalty. If your pulled over for weaving and found to be drinking, impound the car for 24 hours and fine the driver. I'm more concerned with the people driving under legal prescription drugs than anything else.
