In the linked press-release, they call equally for "intelligent speed adaptation systems", which I think would annoy a much wider proportion of the country than alcohol detection. I remember decades ago being amazed that Japan's commercial trucks had lights on the outside of the cabs that showed how fast they were going to aid speeding enforcement. A signal of wrong-doing, rather than a lock on wrong doing. Maybe that's the trick to adoption.
