I have race pedals in my car,and in their defense, they work rather well to position the brake and gas pedal very close together for heel-toe. The original brake and gas pedals were very small and very far apart. :-) After becoming acustomed to using those pedals I tried going without and it was simply much more awkward to drive.

I don't see the purpose of putting them on an automatic car, because then it's attempting to look like you have a manual transmission.
