It wasn't that long ago these devices weren't mandatory and they'd just suspend your license.
I am actually curious now whether that was more effective since the offender had to endure the judgment of the person in their life giving them a ride to work.
I don't understand why this is obviously untrue. Do we have any reason to believe that those people didn't just... continue to drive with a suspended license?
Not to mention DUI is a fairly recent development. In the 20th century, it was pretty easy to drive drunk and get away with it.
