Strange, because most likely the majority of drivers also walk at least a short distance around the same cities they drive into.
In the US in particular, eyballing the number of cars and the number of pedestrians in images of places like New York etc that I've seen, it's very hard to believe that there's a clear line separating all those people walking about from all those people who drive cars, other than the specific time of day they do one or the other.
So you'd think that being careful around pedestrians should come naturally to most drivers, if nothing else because they'd want other drivers to be careful around them as pedestrians also.
