Could you add one-way roads? (Love the game, btw - I've spent way too many hours playing it!)
I'm glad you like it, thanks! One-way roads is a little hard with the current car pathfinding, unfortunately. If I ever revamp that aspect, it's a possibility, though.
(Little late) but it would be nice if there was like a one-way gate system instead of a true "one-way road"
