Intersections are where many pedestrian injuries and fatalities happen, due to "inattentive" motorists. The reality is the motorists are probably attentive to other vehicular traffic, which poses a much greater risk to them but poses a huge risk to pedestrians.

Then there are the agressive motorists. I have seen motorists intentionally[1] accelerate towards school crossing guards. People seem to get impatient when being held up in traffic, even when it is a product of their own decisions (like driving past a school on a residential side street when school is starting for the day).

[1] Of course, I don't know their actual intentions. Yet I have difficulty interpreting a vehicle that is creeping slowly into an intersection then suddenly accelerating towards a safety vested person as anything other than a deliberate act.
