I used to ride 25 kms (16 miles, give or take?) to and from work, every day. These distances aren’t extreme eitherloads of kids would (and do) drive that to school every day as well.
The thing that makes that possible is safe and comfortable bike lanes. More than 30 kms? use busses. If you have a good public transportation system, these busses will have direct connections and drive every 15-30 minutes during school hours.
I know, this sounds insane in the US but that is because car manufacturers have brainwashed US citizens with the nonsense that this is how it must be. Your cities are godawful, all of them, because every city is Designed for cars, not for humans. If you get into a city designed for humans you’ll be amazed. I know because every American is amazed by how beautiful cities can be when they see them.
