Please note that we don't like requests for busses and maps here in the forums
The reason is quite simple: Nobody will start building a map / a bus becaue of your wish, because either someone already started a project with his own ideas or he is not able to do it. At least that's the way it happened in the past.
So please understand that I will close this topic, wait for the desired add-ons to be released or try it yourself (in this case "good luck!").
