I guess you can kinda fake a valet mode if you modify the driver demand pedal request tables in the PCM tune. (or just get one of those pedal commanders) Would kind of work like sport mode does where you can have a laggy pedal feel that you limit in normal mode but in sport it can be spirited and unlimited. Although nothing from preventing the driver from hitting the sport mode button. IMO not really needed on a bone stock RT.
