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...
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.
