If the question were, “how do you think this rule should be applied to a park in your neighborhood” I think agreement would much more achievable.

There is no clarity on what the context of the application of a rule is.

Is an ambulance a vehicle in the park? Of course. Should the rule apply to an ambulance on duty in an actual park? Of course not.

Is a memorial tank a vehicle in the park? Obviously. Would some people object the memorial? For sure. Likely because they don’t like tanks in the park, not because of the vehicle rule, however they may use the vehicle rule to object.

So - amazing data. Wrong question.

I propose that the differences in opinion are likely differences in understanding the ill-defined context of the question.
