First of all I love this mod. I'd almost rather have these guys than the vanilla bots.
However, unless I forget to "disable" them by putting them in my trash slots, they suicide whenever I'm in a vehicle. Especially trains can wipe out a whole legion of these guys if you pass some not-fully-constructed stuff.
Any chance you could disable them in a vehicle? Or at least have them hop out in the direction of the thing they're going to construct?
