I have kids, and I know hundreds of parents across large portions of the country. None of them have these issues.

A person driving down a private road and threatening to call CPS because they can't see the parent is not rare?

And the parent poster didn't just say someone threatened to call the cops, they said that they would be jailed in two very specific circumstances where jailing him would have led to very negative consequences for the arresting parties in anything beyond the immediate term.

Many people are stupid, and do stupid things like calling the cops for no valid reason at all. Those people are annoying and can be ignored, and I would not be remotely surprised by any pseudo-anonymous person doing something stupid. What would surprise me is the cops actually responding to the call and making the decisions that the other poster claimed, with a few exceptions where I would be much less surprised.

Since he only responds to questions with tangential rants, we'll never know for sure what happened.
