Having no trees does NOT make the game look terrible. In your opinion yes, but not as a whole. Personally, I'd rather do away with the trees and a lot of other pointless crap. No vegetation shouldn't even have to be a mod, it should be included in the game under graphics. Maybe in the future, if someone can figure out how to stop the cars from becoming one with trees when you crash into them, then maybe they'd have a purpose, but as of now, they're just to reduce fps for those who don't spend every dollar they have just to have trees.
