Wishlist for the next Gold update

[Ocito80]

I know people grumble about AI-movement, including myself, in that the current algorithm can take units off the roads and into the fields. Is it possible to implement a transport only on road function? If units in RR mode can only move along rail tracks, could something similar be applied to road movement?

I know for me, improving this feature in game would make games like France'40 far more enjoyable.
