What a funny future it'd be, if we have to wear something distinctive (giant QR codes?) so we don't get killed outside. As a side effect it would make tracking us much easier...
It would be less inconvenient than what I already have to do to avoid being killed by human drivers. Getting to the other side of a street according to regulation procedure can easily require taking a 10 minute detour. It can be worse than that in the suburbs.
I suppose this differs depending on location and what your perspective is. Here, it can be quite a chore for human drivers to avoid killing pedestrians. They'll just wander out across the crosswalk, nevermind that their walk-light is red, and proceed leisurely across without a care for the speeding traffic (that has the right-of-way to begin with).
To say nothing of drunks.

Anecdotally, I do also remember, as a pedestrian, waiting for 10 minutes or more in subzero temperatures at an un-managed T crossing (crosswalk but no lights), waiting for an opportunity to cross. Traffic just kept coming and coming from all directions; this was a frequent problem at the time of day I needed to cross. I suppose there's opportunity for improvement on both sides.
You seem to be joking, but isn't that pretty much the SQ? Not universally, but there is a lot of clothing incorporating high-viz features. Most prominent in children's clothes and work clothes, but I've seen reflective material that is almost invisible during daytime being used in business coats, apparently with an eye towards bankers on bikes and the like.
That is why you don't wear purely black clothing in winter and why visibility vest are a thing (think French yellow vests). Or why as a cyclist you want reflective stripes. Funny present.
I really hope that gets verified before people start doing this (and I'm sure some will). Being classified as a lens flare / visual artefact is not a great way to die either.
It's just 'license plates for people'. And driving without a license plate is already illegal in many places. It would be a small step to require citizens to wear their nameber clearly visible at all times when outside. The penalty for failure would be a bit harsh. But on the plus side, all the corpses would be unidentified, so technically no-bodies...
