I know that fernbus is acclimated in Germany, but i would like to add this things: (apart from those already mentioned) (limitations are bad for simulation games).
-Disable speed limit 100
-And most important, sequential or manual transmission for keyboard, I like to choose the speed or gear when I drive.
And greetings from South America , i love this game, i was bored of playing Ets 2 with bus mods XD.
