While only a single road type per tile would make some things easier, it would also force a single tile owner. Especially in regards of town owned roads this would be a trade-off to be carefully examined.PikkaBird wrote:Was dispensing with a separate "tram layer" altogether considered inappropriate? Otherwise, it seems pretty straightforward; road/tram-NewGRF and road/tram-vehicle GRFs should interact with each other in exactly the same way rail and rail vehicle grfs do.
Retaining the current two types isn't that hard conceptually as long as you give vehicles two road types for surface and power, respectively.
