Flipping Rule

[MaGiC_PiKaChU]

I was wondering...

Let's say robot A is a tall robot with a high CG.
Let's say robot B is a low bar robot.
And C is a low bar robot able to upright itself

If A gets tipped over easily, because of their design, is that a strategy aimed at giving opponents red cards? Should the refs be more indulgent about moderate defense played on A that causes tipping?

If C gets tipped over, the same way B would get tipped over, but C is able to flip itself back on its wheels, would there still be a red card?

What if C decides to stay in that flipped position, like B would do because they can't do otherwise, would that be a violation of G11?

How unfair is it for teams who planned on being able to flip back if they got tipped over?
