Introduce the Scandinavian style breathalizers that are directly linked to your ignition... If you're driving drunk you shouldn't be fucking driving ever, end of. You're a death threat to everyone else on the road and do not deserve the privilege to drive. Driving is not a right, it's a privilege.. if you break that law then suffer the consequences cause you're a liability to everyone else on the road.

Yes there should be rehabilitation involved in some way or another for people with duis, suspended licenses, etc.

I dont believe incarceration is deserved unless you end up killing someone while DUI.
