About space stations, ambulances, matchbox cars, and the rest of it I'd venture yes. The only one that seemed remotely jurisdiction-dependent was bicycles.
Can you name a single real park that denies entry to police or ambulances or wheelchairs?
Uh... yeah? Are you aware some parks are dangerous? I just spent Father's day on a narrow boardwalk through a swamp. No vehicles allowed in there of course including emergency vehicles and wheelchairs. If something bad happens, help must arrive by foot. I mean at this point it just sounds like you haven't been to many parks. Parks can vary wildly and so do their rules.
