(Not the patent) I'm very much pro letting children roam freely, but police intervention for walking or driving with your own child is clearly overreach. The good intention does not change that.

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.
