It is a self-correcting problem: these pedestrains won’t be present in the next dataset.
I worry what will happen when this idea breeds with the "why worry about privacy if you've got nothing to hide?" fallacy.
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.
