I predict that flipping will happen regardless of 'tippiness'. Two line-following robots on opposing alliances will meet on the mountain in autonomous. One will probably flip. The other will probably drive on top of the flipped one. More [tragic] hilarity would ensue if both flipped backwards.

Other than that, we teach that center of innertia is what we want to keep low; CoI and CoM are the same exact thing, yet CoI implies an object is in motion and can be 'pulled' parallel to the ground. Teaching this gets students to consider dynamics of design as the drive train rapidly accelerates.
