I tend to drive with my knee against the door, heel on the floor in front and slightly left of the go pedal and use the right side of my foot behind my toes on the bottom of the pedal so it limits the movement of my foot when bouncing. When I need more throttle I can roll my foot across the pedal to the ball of my foot and further depress the peddle. Kind of hard to describe, as I type it, but works for me.
