Double school bus spending, ban parental pickup or drop off, organize walking school buses for closer kids, give out free child transit passes... poof! The morning and afternoon traffic jams go away.
Have you never attended a school board meeting? Even if you had a hundred times more influence in this world and spent the rest of your life focused solely on this goal, I wouldn’t wager higher than 50/50 odds for actually implementing this in the typical school district, for more than a few weeks.
Your children will get a better education, in far fewer hours, without the commute, without suffering under the prison bitch culture of the public school social heirarchy.
If your child is even just slightly neuroatypical, sending them to public school is child abuse, and you are a bad person, full stop.
You are no different from the guy who drinks a fifth of whiskey and beats the shit out of his kids - you're just keeping your hands clean by outsourcing the beatings to the kids on the playground.
