I'm against a device that may or may not record me or take my health stats and report them to a central database every time I get into a vehicle. I don't trust this not to be used as yet another automated surveillance tool for the government. if there is one thing I don't trust the government with, it's visibility at scale.
If we had guts, we would ban bars from selling anyone more than three drinks, and ban bars from serving anyone who has had a drink anywhere else that day. (or something, I'm brainstorming).
