Silly idea: inverse mode?

Hi again, just a quick idea I've had for a different powerdown this time, one which inverts the left/right steering sense & maybe also the brake/accelerator, although it might be too tricky for a player to handle both at once. It sounds like an easy thing to implement from a non-programmer perspective. Perhaps the players screen colours could invert whilst this powerdown is active or something bizarre.
Just imagine driving along then you get the powerdown, perhaps after a countdown like the current dynamite one & you then have to then steer left to go right & vice-versa, and then back to normal once it wears off.

Sorry if this has been suggested before.
Actually now that i think about it, did Skunny Kart have something like this, the green or red potion maybe?
