I would love to drive on the steep streets of San Francisco in this game. Tell me what you think about the idea and/or if you are able to make a San Francisco map.
The upcoming West Coast USA map is based on San Francisco. It's not an exact copy of it, but it should work for you. It isn't released yet, but it should come in one of the next updates. There also is San Frisco, which was inspired by San Francisco ( https://www.beamng.com/resources/san-frisco.2431/ ), but I did not try it, so I can't tell how good it is.
