1) In vanilla game tanks get logistics slots too from Logistics Network research. None of the vehicles have them after installing this mod. It is very useful to auto-supply tanks with fuel, ammo, and to clear their trunk from unnecessary items like wood, stone etc. We use vehicles for even building, carrying belts and all those things player would.
2) In vanilla game i can drive vehicles remotely (click them from main map), but the button is not there with this mod. It was added so that you can somewhat defend your base from surprise attacks when visiting a different planet in Space Age.
I didn't get to spidertron with the mod yet but i assume it still has both 1) and 2).
