If the penalties for impaired driving are going to be as tough as they are, seems fair that the limit ought not to be, "maybe impaired a little". I guess there could be different penalties for different BACs, might work better.

Or they could be tied to the consequences. Crash and injure someone else at 0.08 should probably be treated differently than being flagged at a DUI checkpoint with no apparent impairment at 0.08.
