For your consideration ...
The point being, no matter how many are caught driving while DWI/DUI, it's a revolving door, for THOSE that are caught. Without very significant and substantial consequences, driving drunk or driving under the influence numbers will never ever go down. Which is why the focus should be on incarcerating those that DWI/DUI that injure or kill someone, or destroy someone's property, for very long periods of time.
And since, as its been said, that implied consent is given to have an alcohol test, breath analyzer, blood draw or whatever, anyone getting into an accident, with police called to the scene, regardless of who was at fault, all parties should be field tested for sobriety as part of the accident report. This alone might, might, slow this problem down.
