For many teams (like mine when I was around), the drive team and scouting were separate entities, and I wouldn’t know whether a team abandoned the plan until I met with drive team the night after. That being said, if I really had doubts on a team’s tendencies for this kind of thing, I would ask other alliance partners.
Also, I can say from experience that putting together an alliance that works well together is crucial for an alliance captain, even if it means they take a back seat. Back at CHS DCMP 2016, we played defense as an alliance captain even though we could put quite a few boulders in, and we came a broken robot away from winning the event. Selflessness can go far.
