When you are being charged by the rhinoceros, do you consider if the grass it charged from moved according to your knowledge of how grass should move when a rhinoceros charges through it OR do you get the hell out of the way?

In combat, your opponents probably aren't paying attention to those very insignificant things. Insignificant compared to a battleaxe speeding towards you head, anyway.

In a non-combat situation the viewers might have time to notice inconsistencies, but not when most illusions are being used.
