#4 Can't you just jump onto the tractor while it's running? Haven't tried this in automated, but when my friend drives the truck, I just ride on top.
I don't agree with the other things, but I will say that a road building option would be nice. One that lays road, and the other would be maybe to demolish to make an even plane. So you could terraform the roadway then lay the asphalt or whatever..... instead of haveing to use foundations everywhere. With this option you could still have hills and stuff and not have block like formations everywhere, though the clearings would be done in a grid as per rest of game.
