Reflection rotation on a mirror

[briareos_kerensky]

Good day everyone,

I'm looking for a way to rotate a reflection shown by a rear-viewing mirror with a slight bend. This bend is causing the reflection to rotate; if I rotate the mirror and have it perpendicular to the horizon, the reflection is shown "straight".
Is there any way to counter this rotation in the reflection without moving the object or removing the bend?

I am uncertain if you can fake it without actually baking the "straight" reflections and projecting them as you wish. Though not physically correct, give it a try.
