What about households with teenage or adult children, live in parents, etc? What if I had a live in father that had more than 1 DUI and no car, but I occasionally let him drive my car? Would I have to DUI my car?
The point I am trying to make here is that a person's car can be driven by many people... DUI on the driver's license would make more sense (honestly, I question why people with multiple DUIs still have driver's licenses though).
