Can't help but think that this is just swinging things in the opposite direction.
In French cantons you can bring your kids to school, you can drive them there and there are spots for stopping and all respective signage. But there is indeed a lot of very young kids walking to school.
The neighborhood is safe enough and the community is cohesive enough that kids can congregate along their way to school: go to their friend's house, meet at a park, etc.
It's researched enough that you can go and learn about it and challenge your feelings.
And even as a German who already spent a lot of time in Switzerland, I've never heard of anything like that.
To join in on the therapy speak: it is very good to challenge one's feelings, let go, and then, by the merit of reason, realize that police intervention for spending commute time with your children is bonkers.
It is just a very unreasonable extension of a very reasonable position.
