The disconnect is even if I still drove myself 95% of the time I would still find it vary useful to be able to click a 'drive me' button when I know I am not at my peak. So, I would pay money for the feature. Therefore it's just a financial and legal question if I am allowed to buy one and because they would on net reduce accidents I think they will become widely available.
Now, I would probably not buy or afford gen #1, but it would only take a few years of adoption before I would consider it safe enough to use. And I know there are plenty of people willing to test the first 50 billion miles to 'work out the kinks'.
PS: Over 5 years there is millions of people would literally gain than 5k in direct utility from the I am drunk drive me home button even if that's the only thing it did. But, while less common and far more important is the it's 2am I am tired just get me home. Both of which pale in comparison to the I am still sleepy drive me to work button.
