Consider guns. A felon cannot be in possession of guns legally, and the doctrine of constructive possession means that a prohibited person can be charged with unlawful possession of a firearm if a lawful owner in a household leaves a gun accessible to the prohibited person.
Perhaps it should be a serious crime for a convicted drunk driver to be in or around a car where the ignition device could be in the prohibited person's possession.
My technological ideas were along those lines. Basically allowing them to continue to own their automobile, but not to drive, and perhaps not to buy one, because forcing them to sell their cars is hard to implement (though maybe worth it). And also preventing them from operating cars owned by other people that are stored in their residence or workplace.
