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.
