It's called an interlock, and the snippet posted above said they *weren't* using an interlock or breathalyzer device. Also, interlocks are absolute garbage. They're designed poorly because the majority of the thousands you hand to a mechanic to fix it goes to the company your government contracts. The whole process fucks the driver and the mechanic shop. They barely pay the mechanic's hourly rate per install, and you lose a half dozen labor hours every couple months to keep up with training. The point I was trying to make is that I'm not aware of a technology that exists today that can be attached to your car that doesn't have to draw your breath or your blood. I would assume they probably have a AIs that can analyze video to try and determine if a person is drunk, and that opens another can of worms.
On that topic, Mothers Against Drunk Driving is a fucked up authoritarian organization. My sister got a a marijuana related DUI in the early 2000s, and even though she passed a field sobriety test on camera, the judge threw the book at her. She wrote the judge a letter later asking why he was so harsh, and he straight up admitted to her that a local MADD group monitored all local DUI cases and would lead organized harassment campaigns against judges that didn't impose maximum penalties. I don't know their demographics, but I'd bet it's a bunch of white Karens and balding Jews.
