Fantastic. This is a huge win for everybody. After midnight more than 1 in 8 drivers on the road are legally intoxicated (in the US). Driving is a liberty, not a right. I can understand why this would be limited to alcohol (at least starting out) as alcohol leaves the body rapidly and the diminished capacity leaves with the alcohol. Eventually I would like to see this applied to a variety of intoxicants.
