A lot of comments here about how the intro instructed us to make a very literal interpretation.

I'm not so sure. The exact wording is "You might know of some rule in your jurisdiction which overrides local rules, and allows certain classes of vehicles. Please disregard these rules; the park isn't necessarily in your jurisdiction."

Rephrasing an earlier comment here, but - it's still a park right? On earth? What jurisdiction on earth blocks matchbox cars and space stations? Or even ambulances and police cars, which were the main ambiguous ones? Does some country not allow ambulances in its parks? Are we supposed to include all of modern human culture as a "local jurisdiction"?

The instructions of the game were pretty unclear, that seems to be what's sparking a lot of the debate.
