What I don't think is yet clear to some is this.

If you want drunks on the road, then prosecute those you arrest in a manner which REALLY discourages drunk driving. No pleading out, heavy fines, mandatory license suspensions, and jail terms for repeat offenders.

The way to keep drunks off the road IS NOT to arrest more of them, and then prosecute them with a slap on the wrist. This tactic can only be interpreted to mean you're more interested in collecting fines than ending drunk driving.
