Is it a big part of society though? I would have though children walking to school is fairly independent to the rest of society that needed time-milestones.

Would we assume parents are walking their children to school, hence need to start work later? If that's the case, why does it matter how dark it is?

Most parents of young children are at least seeing them onto school busses if not dropping them off at school themselves themselves. Childcare has to similarly be synced up.

Personally I don’t care much these days but many do.
