Improve the One Pedal function.

Needed improvements: One-pedal sensitivity curve calibration - see the comments below One-pedal mode currently does not work in reverse Break lights are not activated upon deceleration This function needs improvement because the accelerator sensitivity is problematic. When parking and driving at low speeds, it can cause unintentional collisions. Simply enabling the driving mode to switch with One Pedal would be sufficient. The goal is to be able to use One Pedal and the acceleration of Comfort mode simultaneously.
