> And crossing a 50ft+ wide intersection of a 40mph road (which means people drive 50mph) is daunting even for adults, and simply not advisable after the sun goes down.

At least here (California) those intersections have stoplights and pedestrian crossings, so the width and moving speed of the road are not relevant. The cars will be stopped when you cross by walking.

I don't remember exact age but certainly before kindergarden age my child (and all the neighborhood friends in that age range) knew how to operate the pedestrian walk buttons and cross safely.

I fully agree it can be nicer walk when you don't have to cross a larger road. But at the same time, the difficulty of doing it is often greatly overstated. Press button, wait a bit, cross. Done. This is not in the top-100 things I'd like to see improved in society.

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.
