As classified and intended by the sign and societal expectation, a vehicle would be any self-propelled method of transport which violates the space or near space of the park. So a toy car or boat doesn't count, but an actual car or boat would. Just as a bicycle doesn't count but a motorcycle does. And a bit of logic has to be applied for what constitutes "within or near the space of the park" in practice. A plane flying thirty one thousand feet overhead is not even near the park, but a helicopter dropping down so low that the rotors are level with or below the top of the tree canopy is violating the space near the park. And exceptions to rules have to be made under certain circumstances. The ambulance and police car do violate the rules, but have to be given special extensions of jurisdiction to perform the duties wider society assigns and expects of them.
But breaking things down into the very specific definition of "self propelled method of transport" is exactly what doesn't happen for a lot of moderation and enforcement. An offense brought to moderation is often several of those very specific definitions that don't get broken apart into their constituent parts for examination. We stopped using mercury to starch felt hats because the mercury was the problem. If instead we didn't break it down into components to identify the one causing the issue, would we have banned all felt hats or likely just felt altogether? Modern moderation policy dictates bias towards the latter.
The idea of nebulosity as described is precisely why reforms constantly have to be made to enforcement, why automated enforcement is harmful, and why blanket policies on enforcement are a bad idea. Public nudity is generally agreed to be a crime and distasteful, but should somebody be arrested because their clothes were stolen at a changing station? Should a bumper sticker saying "Shoot your local meth dealer" get the driver pulled over because of either threats of violence or public indecency laws that are considered relics of the 19th century and are no longer widely enforced? Moderation in reality is a very simple issue of applying societal biases as rules that becomes horribly unwieldy when scaled beyond a few thousand people. That's because the best moderation is done on a case-by-case basis, as circumstances and context are more important than the infringing action because it's simply one component in a string of them. Obviously you can't do that when you have tens of thousands of users or more and the number of possible offenses grows every picosecond.
