Cars don't always stop at marked crossings. Hell, they don't always stop at marked crossings with lights, or at school bus stops. This isn't an issue of pedestrians just randomly walking in front of cars. Drivers don't always look where they're going, and it's getting worse as people get more distracted by things like massive screens replacing physical controls on the dashboard.
A decade ago, I knew a girl who got hit by a passing SUV while crossing the street to board the school bus. The bus was stopped with lights and signs out on a 2-lane road, it was impossible to miss. The SUV driver just decided not to stop and clipped her going 45 mph when legally they should have stopped. Getting hit was not her fault, and I wouldn't be surprised if a lot of cases were similar.
