What I mean is, imagine one political governing in a city - or several - that prefer to have transportation on roads rather then on railroads, thus having less objections when trying to place bus stops or truck stops, but says no more often when trying to place railroad stations. And after a period of years, the political majority changes and the situation is kind of opposite; a green political majority that prefer to have most of the transportations carried out by railroads.
It would add yet another level of difficulties to the game as one is planning a network - which may even have to change once in awhile as the political majorities changes from one time to another!
Not even sure if it's possible to include such a feature in the patch, but in my opinion it would be fun!
