I'm not aware of any technology reliable, trustworthy, affordable, and quick enough to accomplish said goal without regularly inconveniencing a significantly larger portion of drivers who may need their vehicles in other emergencies. If you could provide a mechanism that didn't infringe non-drunk drivers rights I'd be more apt to accept this idea.
I'd also need to know an override mechanism exists because it seems like certain rare situations could arise where you need to operate a vehicle intoxicated, e.g. fleeing for your life in defense with a relatively low risk of injuring someone comparatively. I'm sitting at home sipping a scotch and hear an intruder come in who for some reason is an abusive person after me specifically in my life. I phone the police but also decide it's best if I can safely flee the area. Maybe the police could override it remotely, I don't know. Overall the edge cases seem difficult to deal with and infringe on others liberties. We start talking about the needs of the many outweighed the needs of the few and trolly problems with different counts of people on different tracks.
I'm just throwing some hypothetical out, it may not be good, but my point is that rare situations can occur and because you were partaking in a legal activity like drinking, due to an emergency change in situation that wasn't predictable, you suddenly need to drive because the risk is now higher than drunk driving. Perhaps a tornado is approaching your house or abusive spouse is out to kill you...
