> The cars will be stopped when you cross by walking.
You live in a place with some combination of far more traffic enforcement or far more conscientious drivers than me.
All I see when I look around is a sea of people glancing up and down between the road and their phone. It would be negligent to let my kids cross an arterial road, especially after dark.
Not sure about far more conscientious, but people do stop at red lights. Seeing someone run a red light is very rare, maybe once every 3-4 years. And even those aren't blatant, they are people trying to get through before the red but failing. So what I do (and teach the kids) is that when the pedestrian crossing goes green (or white, technically) then wait a second, look left & right, and if everyone is stopped, then cross. That eliminates the risk of someone trying to rush through in the last second, and at that point it is perfectly safe to cross.
