Personal growth, his ass!
As one could expect, one particular guardian mecha was entirely against this part of the narrative.
Now, to be fair, Sid most definitely understood the problem and the fact that they weren't particularly suited to fighting in such tight spaces like a subterranean tunnel.
After all, mechas were primarily designed for combat in environments where they could maneuver freely, and while their frames were more than capable of withstanding the occasional collision, that didn't mean they should deliberately go around smashing themselves against walls or each other, especially when there were far better ways to make use of everyone's time and effort!
