I have noticed there are no Chicago street courses in BeamNG yet, or good NASCAR street courses. I think they would be great tracks for this game, but I can't mod. Would anybody be able to make this?
Crafting maps is extremely difficult. And also there's so many copyrights on even the design and locations of real life cities. I'm sure that's why West Coast USA is ambiguous. Landmarks and businesses in Los Angeles, Chicago, New York City, etc often want to be paid for their use. But sure it would be nice to have some more ambiguous locations that look like like NYC, Paris, London, etc. But as I said it's a laborious process to create maps.
