Being solution-based still isn’t going to help kids who live miles from the nearest bus stop catch a regular bus. A complete reorganization of our towns and cities to have bus access for anyone might be nice, but then there’s the parents who really wouldn’t want their kids going on a public bus.
Lots of the United States is quite rural, so a bus service would never be able to pick up all of those kids. Only school buses can since the school bus routes are specifically designed to pick the kids up where they are.
