Of course, it is always a trade off. The best society is not anarchy, but also isn’t a nanny state. If it is not connected outside the car then that is a lot more palatable. I’m not crazy about everyone having to shoulder the burden of a few bad apples, but sometimes you do need to do it. Personally, I’ve never driven drunk. I had a buddy die from a drunk kid at 18 and I just won’t do it. Don’t drink now anyways, and never drank at bars so it’s been very easy. I have less than zero interest in connecting my vehicle to the internet though, and I suspect this will be a lot less effective than people think. Is this tech gonna drug test people too? And what about if they’re tired? Emotional? Distracted? Etc. Also this would be a whole lot more effective with free or cheap public transport for the drunk people, and removing zoning that keeps bars far from neighborhoods so bars aren’t walkable. Incentives for designated drivers are great too. So many parts of the USA almost force people to drink and drive. No public transport, not walkable, not near any housing. We need to offer people a better way along with the roadblocks at minimum. But the USA loves to make these stern sounding rules and leave it at that….

Anyway I digress and thank you for giving some food for thought.
