I think the courts should impound the vehicle involved in repeated drunken driving for a period of at least several months. Subsequent violations should result in longer impoundment or the outright sale of the vehicle.
If the vehicle is owned by another party, the vehicle could be returned to the owner if they are willing to file auto theft charges, and assist in the conviction on the driver.
Failing in that, increasing mandatory jail terms incrementally based on the number of repeat offenses would at least limit the opportunities to repeat the offense. This will save lives.
Yes, I am fully aware that there a number of bleeding hearts out there who feel that counseling is the only answer. Doesn’t seem to be working, does it?
