I feel like this would be a nice mod if it was the precursor before trains.
say you can setup truck stations for medium distance transportation without having to make rails. You could have trucks ferry larges amounts of stuff across the factory using roads (they can drive anywhere but faster on concrete)
often times i have a large amount of items I want to send across my base (iron/copper to liquid areas) that I dont really want to have to run a belt all the way across for each item. Being able to setup automated truck deliveries would be fantastic and fit the theme of the game.
Trucks are a very important function of shipping but are completely ignored in factorio
