I find it interesting you're doing this one size fits all/loosey goosey approach. I tend to prefer some rigidity, but maybe its time to try something radically different. 

[quote]Distances aren't pinned down with real-world precision. Just like in the comics, cities feel as close or as far as the story requires. A vigilante from Gotham can end up in Hell's Kitchen without crossing half the globe, and a flight from Metropolis to New York might take an afternoon instead of hours. This 'comic book geography' keeps every character within reach of one another, while still allowing each city to retain its own identity and atmosphere.[/quote]
This is the only thing my brain is having trouble coming to terms with (not to mention NYC is not that far from Jersey City which isn't far from when Gotham is generally placed).
