If briefly, yes, I plan to add an interface.
Thank you, I'm glad you like the mod. I've put a lot of effort into it, and my inner perfectionist still won't let me rest.
To keep the codebase clean and simple, I've split the mod into several smaller mods, each containing the logic for individual modules that are unrelated to vehicle control. This series of mods uses the following naming prefix: vehicle-_-mod-name
The main mod responsible for vehicle control is now Vehicle -_- RTS Control.

I've already done a lot of refactoring and code cleanup, as well as optimized many parts of the code. However, a few minor issues still remain, and I'm still working on fixing them.
Yes, I've also considered adding an interface that would let you issue commands to vehicles to move from point A to point B. I'll add this feature after the release, once the new set of mods is ready.
