the idea is great but not better do a simple map that before download the main file of the mod will be apply first on the screen then when you start the game you start on the empty place which contain a bunch of flag which you must pass but do not fall or crash them then if you pass all the places with flag and white marks on the ground the game throw you simply on normal server something like winter mod but map must be very small only for test the new drivers
PS: Meybe my idea is not undestable but better show them all of thys in practis then do for them test which most of them after time will be cheat or something do something like Scania truck symulator but in smal scale just smoll place to passed
......sory for my spelling
