"Competitive North America" Ground Transports?

Here is a preview of the map: https://atwar-game.com/map/?id=35437

Just realizing that there is a bit of vast emptiness in this map that makes it hard to play without spamming Air Transports or staying along coastal areas and rivers when playing anywhere but the Northeast or California.

For the sake of having fun and playability concerns as a player starting in a not so densely populated area of the map, I was contemplating adding a ground transport unit that costed 350 and took 10 units 8 tiles since spamming Air Transports seem too inefficient and costly to be a sustainable solution to this problem.

Here's an illustration of this problem where moving infantry from Atlanta for example keeps you in Georgia and not fighting anyone else:


Here it doesn't seem to be too bad because of sea transports on the East Coast. It just feels weird letting people teleport but honestly Ancient is a really fun map and partially because of the tremendous amount of freedom on the map.


Wondering what others think about this. I want people to have fun no matter what country they pick on this map.
