I do wish this was an option for some data, but emergency care would be an absolute shit show. People can't even remember passwords let alone keep track of keys and devices.

Zero trust device, with emergency channels pre-trusted. Like, the ambulance service is known to your device and can already suck your blood type and whatnot. And the police your name and emergency contacts. Or whatever schema with a similar idea. There's the technology to do this already, but we're lacking awareness and initiative.

Hell no. The fuzz ain't getting my info without reasonable, articulable suspicion that I have committed, am committing, or am about to commit a crime, or if I'm pressing charges and need to ID for that process.

The parent comment was about an accident where you're unable to give any details yourself. Maybe when you're under a truck you'd like your folks to know what happened to you, right? But again, such are implementation details. First let's have that zero trust device, then we can be negotiate who gets to see what and when.

The problem is that it creates a vector for illicit access to the information, and if that vector exists, it will be abused.

I'd rather have society deal with the problems that come with not knowing who's under the truck than the problems that come with state surveillance.
