If I put more than 10/15 add-on cars, the game crashes while its loading or while the car selecting. What should I do?

You have to remove some of them from the game folder because the game isn't able to read too much add-on .ar files, especially the too big ones. More big are the .ar files and less of them you have to put in the game folder to avoid the game loading crash or the game crash while you're selecting a car to play.
