The problem remains people don't know what .04 or .08 means in reality. And putting the burden on people to know before they get into a car is unfair and unrealistic.
So if you don't like making the number .01 because you like wonder bread, make it .02 or .04 In my opinion it reaches the same result. It has to be a really low number so people are on notice that any drinking is too much. Even if you can't "feel it" you still shouldn't drive.
My point is that people don't understand how little it takes to get to .08. And by setting the limit at .08 we are telling people its ok to drink and drive and setting them up to fail.
