When I was dispatching my cops were constantly pulling drivers over who were revoked. Sometimes their DMV entry showed multiple revocations spanning year after year as the license was extra-super-mega-revoked upon each subsequent violation. On occasion their car would get towed but generally they would get a licensed driver to collect the car and they'd pay their fine and keep on truckin'. One fellow had six DUIs when we nabbed him for lucky number seven, and the only reason he stopped driving for a while was that his car had gone unregistered since the 1970s and we impounded it.

Any crime related to substance abuse and addiction is unlikely to be affected by increasingly harsh penalties, but by that measure people who don't give a poo poo are similarly unaffected. You can discuss penalties until you're blue in the face but the responsiveness is on the part of the offender and when it comes to people's desire to drink (and to drive drunk) you won't accomplish anything.
