> That doesn't mean the ambulance driver is in the wrong, though. There could be other rules that supersede that rule. We aren't told of any, though, and are simply asked about that one rule.

Yeah, this was my thought exactly. Anyone who says an ambulance is allowed is not following the rules of the game, which say to only consider the "no vehicles in the park" rule. In a real scenario, there would of course be other rules (the WW2 tank would be there by permission of the park management, for example). But if you only consider the one rule (as you were told to) then the answers are imo quite straightforward.

I agreed with 93% of people when I played the game, so it sure seems to me like there's broad agreement on this.
