If they don't have a regular bus system that works then that's what they need to start working on first. I'm convinced that it can be made to work if they are solution oriented instead of only looking for reasons why it won't work and stopping there.

Where I live, buses have dynamic routes. You go on an app to book a journey, then you get a time and place to be where the bus will pick you up (plus a drop-off point). It works for school kids as well as anyone else.

90% of Americans live in cities or towns, the percentage that aren't driven to school is much much lower.
