Impaired driving is one of the very few things that I think warrant punishment, of a sort, prior to conviction. Impaired drivers are demonstrably not in any condition to be handed back a vehicle when they are stopped. They famously don't learn from being caught. The worst of them don't care, at all, about thew sanctions that have already been placed against them and they continue to drive afterwards.
By comparison someone who has been caught while "stunt driving" (speeding) is already no longer speeding.
