This is already an excellent game and I have lost many weekends to playing but would really be nice if community made routes could be added. tools and map building tools to allow the community to build routes that are submitted to a moderation team / QA team before being made available to download in game. I think this would really expand the game and the community.
Well that is in the works, it is called 'the Editor' And we will have to wait for it for an eternity, as it has been in the work for YEARS
