This isn't like putting a couple of 10 year olds on a commuter bus.

Schools will put 3 highschoolers in a tiny row together without an AC in peak 3pm heat and toss them around streets with heavily outdated seatbelts nobody wears. I've had to sit with half a buttcheek on the seat and hold on for dear life many times.
When there is an AC it might drip water on top of you. Not to mention I've seen like 3 fights, one of which I was sitting next to the dude by chance.
I also had a time where they heavily underestimated how many busses they needed and every row was 3 kids to a seat and I had to stand in the isle for an HOUR until they could get a second bus. They wouldn't let us off and people on the bus had work they were scheduled to be at.

This isn't a like commuter bus, it's a prison bus packed with sweaty teenagers. This is why nobody in the US wants to use busses, because the only experience they've had with them has been AWFUL

edit: this turned into more of a personal vent of my school rather than a thought through response to your comment 😅
