You are definitely not getting 280+ FPS everywhere. Gridmap with a Covet, maybe, but not WCUSA with a T-series, a trailer and 2 cars in it. About the "good idea"- nope. That'd be a lawsuit about to happen. Besides, BeamNG cars are often more detailed when it comes to the models- every part of the suspension and everything under the hood is modeled, unlike many of the models on Turboduck. Using cars that are inspired by multiple real cars is a good idea because it eliminates the issue of "plz add car X its my fave and car Y (it's competitor) is already in the game its unfair". One car can fulfill multiple roles.
